operates across a 9:1 bandwidth. This is an ultra-broadband mixer
spanning 2 to 18GHz on the RF and LO ports with an IF from DC to 3
GHz. Up to 40 dB of image rejection is available due to the excellent
phase and amplitude balance of its on-chip LO quadrature hybrid. Both
wire bondable die and connectorized modules are available. For a list of
recommended LO driver amps for all mixers and IQ mixers, see here.

Image Rejection and Single sideband performance plots are defined by the upper sideband (USB)
or lower sideband (LSB) with respect to the LO signal. Plots are defined by which sideband is
selected by the external IF quadrature hybrid.

I output means that the IF output signal is measured at the I port of the mixer and the Q port is
loaded. Q output means the IF output signal is measured at the Q port of the mixer while the I
port is loaded. SSB in phase input means that a low frequency quad hybrid is used to split the
input, and the in-phase component is applied to the I port and the 90-degree component is applied
to the Q port. SSB out of phase input means that a low frequency quad hybrid is used to split the
input, and the in-phase component is applied to the Q port and the 90-degree component is applied
to the I port.

I+Q measurements taken with an external quadrature hybrid attached to the I and Q ports of the
mixer. Orientation depends on up conversion or down conversion measurement.

3.6.7 Typical Spurious Performance: Downconversion
Typical downconversion spurious data is provided by selecting RF and LO frequencies (± m*LO ±
n*RF) within the RF/LO bands, to create a spurious output at an IF of 91 MHz. The value of this
spur is plotted against the RF input frequency below. Spurious suppression is scaled for different
RF power levels by (n-1), where “n” is the RF spur order. For example, the 2RF x 2LO spur is 66
dBc for a -10 dBm input, so a -20 dBm RF input creates a spur that is (2-1) x (-10 dB) lower, or
76 dBc.

3.6.8 Typical Spurious Performance: Up-Conversion
MMIQ-0218L
Typical spurious data is taken by mixing an input IF at 91 MHz, with LO frequencies
(± m*LO ± n*IF), to create a spurious output within the RF output band. The value of this spur is
plotted against the RF Output Frequency. Spurious suppression is scaled for different IF input
power levels by (n-1), where “n” is the IF spur order. For example, the 2IFx1LO spur is typically
32 dBc for a -10 dBm input with a sine-wave LO, so a -20 dBm IF input creates a spur that is (2-
1) x (-10 dB) lower, or 42 dBc.

MMIQ-0218L
4. Application Information
4.1 Detailed Description
MMIQ-0218 belongs to Marki Microwave’s MMIQ family of mixers. The MMIQ product line
consists of passive GaAs MMIC mixers designed and fabricated with GaAs Schottky diodes.
MMIQ mixers offer excellent amplitude and phase balance due to its on-chip LO quadrature hybrid.
Up to 40 dB of image rejection (i.e., single sideband suppression) can be obtained by using the
MMIQ-0218 as an image rejection or single sideband mixer. The MMIQ-0218H is the sister mixer
of the MMIQ-0218L. The MMIQ-0218H requires a higher LO drive to operate the mixer. In
exchange, the MMIQ-0218H displays higher linearity (i.e., higher IIP3, P1dB, Spurious
Suppression) than the MMIQ-0218L. Marki H and L diodes correspond to different diode forward
turn on voltages.
Support for the S, C, X, and Ku bands are offered by the ultra-broadband performance of the
mixer’s RF and LO ports. Traditional use of this mixer to do image reject or single sideband mixing
is available with an external IF quadrature hybrid. The MMIQ-0218 is also suitable for use as a
Vector Modulator through DC bias of the I and Q ports.
The RF port and the LO port supports a 2-18 GHz signal. The I and Q ports support a DC-3 GHz
signal. A signal may be input into any port of the mixer which supports that signal’s frequency. This
is the basis of using the mixer as a band shifter.
For a given LO power within the recommended operating range, the RF (in the case of a down
conversion) or IF (in the case of an up conversion) input power should be below the input 1 dB
compression point to avoid signal distortion. The input 1 dB compression point will vary across the
mixer’s operating bandwidth and with LO input power. Careful characterization is required for
optimal performance for each application. There is no minimum small signal input power required
for operation. Excessive RF/IF input power increases non-desired spurious output power and
degrades the fundamental conversion loss. Excessive LO input power can also cause this effect.
The table below describes how to use an IQ mixer and quad hybrid to select a single sideband.

4.2 Down-Converter
A down converter is a mixer application which takes a high frequency small signal RF input, and a
high frequency large signal LO input and mixes the signals together to produce a low frequency IF
output. The fundamental 1RFx1LO outputs present at the IF port are the fLO-RF and fLO+RF tones.
The desired output in a down conversion is typically the fLO-RF term. An image frequency at
fImage=f2LO-RF will also down convert to the fLO-RF frequency. The above illustration shows the relative
location of the image frequency for a highside LO, or the frequency plan for which fLO > fRF.
To use the IQ mixer as a down converter, input a high frequency small signal RF, a high frequency
large signal LO input, and pull the low frequency IF output from the I and Q ports. I and Q IF
outputs will be at the same frequency but 90° out of phase (i.e., I and Q are in quadrature). If only
a single IF output is desired, terminate either the I or Q ports with a wideband 50Ω load.
This is the input scheme was used to take I/Q down-conversion data found in the Typical
Performance Plots section.
4.2.1 Image Reject Down-Converter
An image reject mixer is a mixer which rejects the down converted image frequency from the IF
output. Image reject mixers are constructed using an external quadrature hybrid attached to the I
and Q (i.e., IF) output ports. Using the external IF quadrature hybrid, one can select the whether
the upper sideband or lower sideband signal is suppressed with respect to the LO signal.
To use the IQ mixer as an image reject mixer, input the high frequency small signal RF and a high
frequency large signal LO input. Take the combined I+Q down converted signal through the IF
quadrature hybrid. Select the upper sideband (i.e., suppress the lower sideband) by connecting the
I port to the 0° port of the IF quadrature hybrid and attach the Q port to the 90° port of the IF
quadrature hybrid. Select the lower sideband (i.e., suppress the upper sideband) by attaching the I
port to the 90° port of the IF quadrature hybrid and attach the Q port to the 0° port of the IF
quadrature hybrid.
This is the input scheme was used to take image rejection down-conversion data found in the
Typical Performance Plots section.

4.3 Up-Converter
An up converter is a mixer application which takes a low frequency small signal IF input, and a high
frequency large signal LO input and mixes the signal together to produce a high frequency RF
output. The fundamental 1IFx1LO outputs present at the RF port are the fLO-IF and fLO+RF tones.
An up conversion can select either the fLO-IF or the fLO+IF tones. The above illustration shows both
up converted sidebands with either an I or Q port input signal.
To use the IQ mixer as an up converter, input a low frequency small signal IF input into the I or Q
port, a high frequency large signal LO input into the LO port, and pull the high frequency RF output
from the RF port. Input into the Q port will result in a up converted signal that is 90° out of phase
with the up converted I port input signal. If only a single IF input is desired, terminate either the I
or Q ports with a wideband 50Ω load.
This is the input scheme used to take I/Q up-conversion data found in section 3.6 Typical
Performance.
4.3.1 Single Sideband Up-Converter
A single sideband mixer is a mixer which suppress the up converted image frequency from the RF
output. Single sideband mixers are constructed using an external quadrature hybrid attached to
the I and Q (i.e., IF) input ports. Using an external IF quadrature hybrid, one can select whether
the upper sideband of the lower sideband signal is suppressed with respect to the LO signal.
To use the IQ mixer as a single sideband mixer, input the low frequency small signal I+Q IF signal
into the IF quadrature hybrid. The IF quadrature hybrid is attached to the I and Q ports of the IQ
mixer. Input the high frequency large signal LO input into the LO port and take the up converted
high frequency RF signal from the RF port. Select the upper sideband (i.e., suppress the lower
sideband) by attaching the I port to the 90° port of the IF quadrature hybrid and attach the Q port
to the 0° port of the IF quadrature hybrid. Select the lower sideband (i.e., suppress the upper
sideband) by attaching the I port to the 0° port of the IF quadrature hybrid and attach the Q port
to the 90° port of the IF quadrature hybrid.
This is the input scheme used to take single sideband up-conversion data found in section 3.6
Typical Performance.

4.4 Band Shifter
A band shifter is an unusual application for a mixer. Band shifters take an IF signal and shift it to a
different band, generally to either avoid interference or for rebroadcast at a different frequency.
For cases in which the desired band shift cannot be employed by using a standard up or down
conversion scheme, an exotic input scheme is required.
A passive diode mixer is reciprocal on all ports. The LO and RF ports support a 2-18 GHz signal.
The I and Q ports support a DC-3 GHz signal. 2 signals input into any combination of the 3 ports,
RF, LO, or IF, will result in an output signal at the 3rd port. In addition, an output signal will be
present at both input ports. By using the IF port, as a large signal input port, low frequency LO
applications can be supported.
The diagram above shows an IQ mixer being used as a band shifter. Using an IQ mixer as a band
shifter allows for sideband suppression. This is identical to using the IQ mixer as a single sideband
up converter. However, the large signal input port is now into the I and Q ports instead of the LO
port. Selection of the output tone is done through the orientation of the LO quadrature hybrid.
To use the mixer as a single sideband band shifter, input a low frequency large signal LO into the
external LO quadrature hybrid. Input the high frequency small signal IF signal into the LO port and
take the high frequency RF output from the RF port. Select the upper sideband (i.e., suppress the
lower sideband) by connecting the I port to the 90° port of the IF quadrature hybrid and connect
the Q port to the 0° port of the LO quadrature hybrid. Select the lower sideband (i.e., suppress
the upper sideband) by connecting the I port to the 0° port of the LO quadrature hybrid and
connect the Q port to the 90° port of the LO quadrature hybrid.
This is the input scheme used to take band shifter data found in the Typical Performance Plots:
Band Shifter section.
Using this input scheme requires careful accounting of which input signal is injected which port.
Injecting a signal into any port which does not support the correct band will lead to a degraded or
no output response. Abide by the maximum DC current input into the I and Q ports of the mixer or
otherwise irreversible damage to the mixer will occur.
The limiting factor in use of the mixer as an image reject band shifter is in the bandwidth of the
external LO quadrature hybrid and bandwidth of the I and Q ports.

4.5 Vector Modulator
A vector modulator is a device that can modulate an input signal’s amplitude and phase. Similar to
using a double balanced mixer as a phase modulator or phase shifter, an IQ mixer can be used as a
vector modulator. An IQ mixer can be used as a vector modulator by inputting DC current into
both the I and Q ports.
Injecting DC current into both the I and Q ports forward biases both mixer cores and causes them
to be shorted. This connects the RF and LO baluns allowing the input signal to pass from balun to
balun without a frequency conversion. Modulating the DC current into either or both I and Q
mixers causes both the phase and amplitude to modulate based on the polarity of the input current
and the magnitude of the input current. Modulating only the I or Q mixers causes the device to
behave as a biphase modulator (i.e., the device can only swing the phase from +90° to -90°).
To use the IQ mixer as a vector modulator, supply a DC current sufficient to turn on the mixer
through both the I and Q ports. An example bias condition is given in section Error! Reference s
ource not found. for the MMIQ-0218L with the phase set to 0°, 90°, 180°, and 270° for a
10GHz input. Current limiting the DC source to the maximum DC current value found in section
3.1 Absolute Maximum Ratings is recommended to prevent irreversible damage to the vector
modulator. The typical DC current required to turn on the vector modulator is <30mA.
This is the measurement scheme used to take vector modulator data found in the Typical
Performance Plots: Vector Modulator section.
It is recommended to sequence the vector modulator by slowly increasing the DC bias until the
vector modulator is operating at the user desired condition.
Near the band edges of the vector modulator, more current than is typical for mid-band operation
may be necessary to achieve the same amplitude and phase shift. This is due to the on chip LO
quadrature hybrid operating near it’s band edge.

5. Die Mounting Recommendations
5.1 Mounting and Bonding Recommendations
Marki MMICs should be attached directly to a ground plane with conductive epoxy. The ground
plane electrical impedance should be as low as practically possible. This will prevent resonances
and permit the best possible electrical performance. Datasheet performance is only guaranteed in
an environment with a low electrical impedance ground.
Mounting
To epoxy the chip, apply a minimum amount of conductive epoxy to the mounting surface so that a
thin epoxy fillet is observed around the perimeter of the chip. Cure epoxy according to
manufacturer instructions.
Wire Bonding
Ball or wedge bond with 0.025 mm (1 mil) diameter pure gold wire. Thermosonic wirebonding with
a nominal stage temperature of 150 °C and a ball bonding force of 40 to 50 grams or wedge
bonding force of 18 to 22 grams is recommended. Use the minimum level of ultrasonic energy to
achieve reliable wirebonds. Wirebonds should be started on the chip and terminated on the
package or substrate. All bonds should be as short as possible <0.31 mm (12 mils).
Circuit Considerations
50 Ω transmission lines should be used for all high frequency connections in and out of the chip.
Wirebonds should be kept as short as possible, with multiple wirebonds recommended for higher
frequency connections to reduce parasitic inductance. In circumstances where the chip is more
than .001” thinner than the substrate, a heat spreading spacer tab is optional to further reduce
bondwire length and parasitic inductance.
5.2 Handling Precautions
General Handling
Chips should be handled with care using tweezers or a vacuum collet. Users should take
precautions to protect chips from direct human contact that can deposit contaminants, like
perspiration and skin oils on any of the chip's surfaces.
Static Sensitivity
GaAs MMIC devices are sensitive to ESD and should be handled, assembled, tested, and
transported only in static protected environments.
Cleaning and Storage
Do not attempt to clean the chip with a liquid cleaning system or expose the bare chips to liquid.
Once the ESD sensitive bags the chips are stored in are opened, chips should be stored in a dry
nitrogen atmosphere.
