HMC7912
FEATURES
GENERAL DESCRIPTION
Conversion gain: 15 dB typical
Sideband rejection: 22 dBc typical
The HMC7912 is a compact, gallium arsenide (GaAs), pseudo-
morphic (pHEMT), monolithic microwave integrated circuit
(MMIC) upconverter in a RoHS compliant, low stress, injection
molded plastic LFCSP package that operates from 21 GHz to
24 GHz. This device provides a small signal conversion gain of
15 dB with 22 dBc of sideband rejection. The HMC7912 uses a
variable gain amplifier preceded by an in-phase/quadrature (I/Q)
mixer that is driven by an active 2× LO multiplier. IF1 and IF2
mixer inputs are provided, and an external 90° hybrid is needed to
select the required sideband. The I/Q mixer topology reduces
the need for filtering of the unwanted sideband. The HMC7912
is a much smaller alternative to hybrid style single sideband (SSB)
upconverter assemblies, and it eliminates the need for wire
bonding by allowing the use of surface-mount manufacturing
techniques.
Input power for 1 dB compression (P1dB): 4 dBm typical
Output third-order intercept (OIP3): 33 dBm typical
2× local oscillator (LO) leakage at RFOUT: 5 dBm typical
2× LO leakage at the intermediate frequency (IF) input:
−35 dBm typical
RF return loss: 15 dB typical
LO return loss: 15 dB typical
32-lead, 5 mm × 5 mm LFCSP package

HMC7912
Data Sheet
THEORY OF OPERATION
The HMC7912 is a GaAs, pHEMT, MMIC I/Q upconverter with
an integrated LO buffer that upconverts intermediate frequencies
between dc and 3.5 GHz to radio frequencies between 21 GHz
and 24 GHz. LO buffer amplifiers are included on chip to allow
a typical LO drive level of only 4 dBm for full performance. The
LO path feeds a quadrature splitter followed by on-chip baluns
that drive the I and Q singly balanced cores of the passive mixers.
The RF output of the I and Q mixers are then summed through
an on-chip Wilkinson power combiner and relatively matched
to provide a single-ended 50 Ω output signal that is amplified
by the RF amplifiers to produce a dc-coupled and 50 Ω matched
RF output signal at the RFOUT port. A voltage attenuator precedes
the RF amplifiers for desired gain control.
The power detector feature provides a LO cancellation capability
to the level of −10 dBm. See Figure 82 for a functional block
diagram of the upconverter circuit architecture.

HMC7912
APPLICATIONS INFORMATION
A typical lower sideband upconversion circuit is shown in
Figure 83. The lower sideband input signal is connected to the
input port of the 90° hybrid coupler. The isolated port is loaded
to 50 Ω. The external 90° hybrid splits the IF signal into I and Q
phase terms. The I and Q input signals enter the HMC7912 on
the IF1 and IF2 inputs. IF1 of the device is connected to the 0°
port of the hybrid coupler. IF2 is connected to the 90° port of
the hybrid coupler. The LO to RF leakage can be improved by
applying small dc offsets to the I/Q mixer cores via the VDC_IF1
and VDC_IF2 inputs. However, it is important to limit the applied
dc bias to avoid sourcing or sinking more than 3 mA of bias
current. Depending on the bias sources used, it may be prudent to
add series resistance to ensure that the applied bias current does
not exceed 3 mA.
4. Apply 5 V to Pin 9 (VDLO1) and Pin 10 (VDLO2).
5. Apply −5 V to Pin 20 (VCTL2) and Pin 21 (VCTL1). Adjust
CTL1 and VCTL2 between −5 V and 0 V depending on the
V
amount of attenuation desired.
6. Apply 5 V to Pin 18, Pin 19, Pin 22, and Pin 25 (VDRF4
,
V
DRF3, VDRF2, and VDRF1).
7. Adjust Pin 26 (VGRF) between −2 V and 0 V to achieve a
total amplifier quiescent drain current of 220 mA.
LOCAL OSCILLATOR NULLING
Broad LO nulling may be required to achieve optimum IP3 and
LO to RF isolation performance. This nulling is achieved by
applying dc voltages between −0.2 V and +0.2 V to the I and Q
ports to suppress the LO signal across the RF frequency band by
approximately 5 dBc to 10 dBc. To suppress the LO signal at the
RF port, use the following nulling sequence:
Biasing the power detector circuitry may degrade the IP3
performance. Therefore, to achieve optimum IP3 performance
it is recommended that the power detector of the HMC7912 be
kept in off mode.
1. Adjust VDC_IF1 between −0.2 V and +0.2 V and monitor the
LO leakage on the RF port. When the desired or maximum
level of suppression is achieved, proceed to Step 2.
2. Adjust VDC_IF2 between −0.2 V and +0.2 V and monitor the
LO leakage on the RF port until either the desired or the
maximum level of suppression is achieved.
3. If the desired level of the LO signal on the RF port has still
not been achieved, further tune each VDC_IF1 and VDC_IF2
independently to achieve the desired LO leakage. The
resolution of the voltage changed on the voltage of the
BIASING SEQUENCE
The HMC7912 uses buffer amplifiers in the LO and RF paths.
These active stages all use depletion mode pHEMTs. To ensure
transistor damage does not occur, use the following power-up
bias sequence:
1. Apply a −5 V bias to Pin 27 (VESD).
2. Apply a −2 V bias to Pin 26 (VGRF), which is a pinched
off state.
V
DC_IF1 and VDC_IF2 inputs must be in the millivolt range.
3. Apply a −0.5 V bias to Pin 1 (VGMIX). This bias can be
adjusted from −0.5 V to −1 V depending on the LO power
used to provide the optimum IP3 response of the mixer.
