High-Gain Vector Multipliers
General Description
Features
The MAX2045/MAX2046/MAX2047 low-cost, fully inte-
grated vector multipliers alter the magnitude and phase
of an RF signal. Each device is optimized for the UMTS
(MAX2045), DCS/PCS (MAX2046), or cellular/GSM
(MAX2047) frequency bands. These devices feature
differential RF inputs and outputs.
ꢀ Multiple RF Frequency Bands of Operation
2040MHz to 2240MHz (MAX2045)
1740MHz to 2060MHz (MAX2046)
790MHz to 1005MHz (MAX2047)

The MAX2045/MAX2046/MAX2047 provide vector
adjustment through the differential I/Q amplifiers. The
I/Q amplifiers can interface with voltage and/or current
digital-to-analog converters (DACs). The voltage inputs
are designed to interface to a voltage-mode DAC, while
the current inputs are designed to interface to a current-
mode DAC. An internal 2.5V reference voltage is provid-
ed for applications using single-ended voltage DACs.

The MAX2045/MAX2046/MAX2047 operate from a 4.75V
to 5.25V single supply. All devices are offered in a com-
pact 5mm ✕ 5mm, 32-lead thin QFN exposed-paddle
packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 3: Radius is defined as (VI2 + VQ2)0.5. VI denotes the difference between VI1 and VI2. VQ denotes the difference between VQ1
and VQ2. For differential operation: VI1 = V

RF Ports
Detailed Description
The RF input and output ports require external matching
for optimal performance. See Figures 1 and 2 for appro-
priate component values. The output ports require
external biasing. In Figures 1 and 2, the outputs are
biased through the balun (T2). The RF input ports can
be driven differentially or single ended (Figures 1, 2)
using a balun. The matching values for the MAX2045/
MAX2046 were set to be the same during characteriza-
tion. An optimized set of values can be found in the
MAX2045/MAX2046/MAX2047 Evaluation Kit data
sheet.
The MAX2045/MAX2046/MAX2047 provide vector
adjustment through the differential I/Q amplifiers. Each
part is optimized for separate frequency ranges:
MAX2045 for f = 2040MHz to 2240MHz, MAX2046 for
IN
f
= 1740MHz to 2060MHz, and MAX2047 for f
=
IN
IN
790MHz to 1005MHz. All three devices can be inter-
faced using current- and/or voltage-mode DACs.
The MAX2045/MAX2046/MAX2047 accept differential
RF inputs, which are internally phase shifted 90
degrees to produce differential I/Q signals. The phase
and magnitude of each signal can then be adjusted
using the voltage- and/or current-control inputs.
Figure 1 shows a typical operating circuit when using
both current- and voltage-mode DACs. When using
only one of the two, leave the unused I/Q inputs open.
I/Q Inputs
The control amplifiers convert a voltage, current, or
voltage and current input to a predistorted voltage that
controls the multipliers. The I/Q voltage-mode inputs
can be operated differentially (Figure 1) or single
ended (Figure 2). A 2.5V reference is provided on-chip
for single-ended operation.

On-Chip Reference Voltage
An on-chip, 2.5V reference voltage is provided for
single-ended control mode. Connect REFOUT to VI2
and VQ2 to provide a stable reference voltage. The
equivalent output resistance of the REFOUT pin is
approximately 80Ω. REFOUT is capable of sourcing
1mA of current, with <10mV drop-in voltage.
gain approaches its minimum value. This appears as
the null in the Typical Operating Characteristics. The
measurement results include rise-time errors from the
crystal detector (specified by manufacturing to be
approximately 8ns to 12ns), the comparator (approxi-
mately 500ps), and the 500MHz BW oscilloscope (used
to measure the control and detector signals).
Applications Information
Layout Issues
A properly designed PC board is an essential part of
any RF/microwave circuit. Keep RF signal lines as short
as possible to reduce losses, radiation, and inductance.
For best performance, route the ground pin traces
directly to the exposed pad underneath the package.
This pad should be connected to the ground plane of
the board by using multiple vias under the device to
provide the best RF/thermal conduction path. Solder the
exposed pad on the bottom of the device package to a
PC board exposed pad.
RF Single-Ended Operation
The RF input impedance is 50Ω differential into the IC.
An external low-loss 1:1 balun can be used for single-
ended operation. The RF output impedance is 300Ω
differential into the IC. An external low-loss 4:1 balun
transforms this impedance down to 50Ω single-ended
output (Figures 1 and 2).
Bias Resistor
The bias resistor value (280Ω) was optimized during
characterization at the factory. This value should not be
adjusted. If the 280Ω ( 1%) resistor is not readily avail-
able, substitute a standard 280Ω ( 5%) resistor, which
may result in more current part-to-part variation.
The MAX2045/MAX2046/MAX2047 Evaluation Kit can
be used as a reference for board layout. Gerber files
are available upon request at www.maxim-ic.com.
Power-Supply Bypassing
Switching Speed
The control inputs have a typical 3dB BW of 260MHz.
This BW provides the device with the ability to adjust
gain/phase at a very rapid rate. The Switching Speed
graphs in the Typical Operating Characteristics try to
capture the control ability of the vector multipliers.
These measurements were done by first removing
capacitors C4–C7 to reduce driving capacitance.
Proper voltage-supply bypassing is essential for high-
frequency circuit stability. Bypass the V
pins with
CC
10nF and 22pF (47pF for the MAX2047) capacitors.
Connect the high-frequency capacitor as close to the
device as possible.
Exposed Paddle RF Thermal
Considerations
The EP of the 32-lead thin QFN package provides a low
thermal-resistance path to the die. It is important that the
PC board on which the IC is mounted be designed to
conduct heat from this contact. In addition, the EP
provides a low-inductance RF ground path for the device.
The test for gathering the curves shown, uses a
MAX9602 differential output comparator to drive VI1,
VI2, VQ1, and VQ2. One output of the comparator is
connected to VI1/VQ1, while the other is connected to
VI2/VQ2. The input to the vector multiplier is driven by
an RF source and the output is connected to a crystal
detector. The switching signal produces a waveform
that results in a 0.7V differential input signal to the
vector multiplier.
It is recommended that the EP be soldered to a ground
plane on the PC board, either directly or through an
array of plated via holes.
Soldering the pad to ground is also critical for proper heat
dissipation. Use a solid ground plane wherever possible.
This signal switches the signal from quadrant 3 (-0.7V
case), through the origin (maximum attenuation), and
into quadrant 1 (+0.7V case). The before-and-after
amplitude (S21) stays about the same between the two
quadrants but the phase changes by 180°.
