HMC8142
FEATURES
GENERAL DESCRIPTION
Gain: 21 dB typical
The HMC8142 is an integrated E-band gallium arsenide (GaAs),
Output power for 1 dB compression (P1dB): 25 dBm typical
Saturated output power (PSAT): 26 dBm typical
Output third-order intercept (OIP3): 29 dBm typical
Input return loss: 12 dB typical
Output return loss: 8 dB typical
DC supply: 4 V at 450 mA
pseudomorphic high electron mobility transistor (pHEMT),
monolithic microwave integrated circuit (MMIC), medium power
amplifier with a temperature compensated on-chip power detector
that operates from 81 GHz to 86 GHz. The HMC8142 provides
21 dB of gain, 25 dBm of output power at 1 dB compression,
29 dBm of output third-order intercept, and 26 dBm of saturated
output power at 20% power added efficiency (PAE) from a 4 V
power supply. The HMC8142 exhibits excellent linearity and is opti-
mized for E-band communications and high capacity wireless
backhaul radio systems. The amplifier configuration and high gain
make it an excellent candidate for last stage signal amplification
before the antenna. All data is taken with the chip in a 50 Ω test
fixture connected via a 3 mil wide × 0. 5 mil thick × 7 mil long
ribbon on each port.
No external matching required
Die size: 3.039 mm × 1.999 mm × 0.05 mm

HMC8142
Data Sheet
THEORY OF OPERATION
The architecture of the HMC8142 power amplifier is shown in
Figure 39. The HMC8142 uses four cascaded gain stages to form an
amplifier with a combined gain of 21 dB and saturated output
power (PSAT) of 26 dBm. At the output of the last stage, a coupler
taps off a small portion of the output signal. The coupled signal
is presented to an on-chip diode detector for external monitoring of
the output power. A matched reference diode is included to help
correct for detector temperature dependencies. See the application
circuit shown in Figure 40 for further details on biasing the
different blocks and using the detector features.

HMC8142
APPLICATIONS INFORMATION
1. Apply a −2 V bias to the VGG1 to VGG4 pads.
2. Apply 4 V to the VDD1 to VDD4 pads.
3. Adjust VGG1 to VGG4 between −2 V and 0 V to achieve a
total amplifier drain current of 450 mA.
TYPICAL APPLICATION CIRCUIT
A typical application circuit for the HMC8142 is shown in
Figure 40. Combine supply lines as shown in the application
circuit schematic to minimize external component count and
simplify power supply routing.
To power down the HMC8142, follow the procedure in reverse.
The HMC8142 uses several amplifier, detector, and attenuator
stages. All stages use depletion mode pHEMT transistors. It is
important to follow the following power-up bias sequence to
ensure transistor damage does not occur.
For additional guidance on general bias sequencing, see the
MMIC Amplifier Biasing Procedure application note.

MOUNTING AND BONDING TECHNIQUES FOR MILLIMETERWAVE GAAS MMICS
Attach the die directly to the ground plane eutectically or with
conductive epoxy.
Transients
Suppress instrument and bias supply transients while bias is
applied. To minimize inductive pickup, use shielded signal and
bias cables.
To bring RF to and from the chip, use 50 Ω microstrip trans-
mission lines on 0.127 mm (5 mil) thick alumina thin film
substrates (see Figure 42).
General Handling
Handle the chip on the edges only using a vacuum collet or with
a sharp pair of bent tweezers. Because the surface of the chip
has fragile air bridges, never touch the surface of the chip with a
vacuum collet, tweezers, or fingers.

RIBBON BOND
0.076mm
(0.003")
MOUNTING
The chip is back metallized and can be die mounted with gold/tin
(AuSn) eutectic preforms or with electrically conductive epoxy.
The mounting surface must be clean and flat.

Eutectic Die Attach
0.127mm (0.005") THICK ALUMINA
THIN FILM SUBSTRATE
It is best to use an 80% gold/20% tin preform with a work
surface temperature of 255°C and a tool temperature of 265°C.
When hot 90% nitrogen/10% hydrogen gas is applied, maintain
tool tip temperature at 290°C. Do not expose the chip to a
temperature greater than 320°C for more than 20 sec. No more
than 3 sec of scrubbing is required for attachment.
Figure 42. Routing RF Signals
To minimize bond wire length, place microstrip substrates as
close to the die as possible. The typical die to substrate spacing
is 0.076 mm to 0.152 mm (3 mil to 6 mil).
Epoxy Die Attach
HANDLING PRECAUTIONS
ABLETHERM 2600BT is recommended for die attachment.
Apply a minimum amount of epoxy to the mounting surface so
that a thin epoxy fillet is observed around the perimeter of the
chip after placing it into position. Cure the epoxy per the schedule
provided by the manufacturer.
To avoid permanent damage, adhere to the precautions in the
following sections.
Storage
All bare die ship in either waffle or gel-based ESD protective
containers, sealed in an ESD protective bag. After opening the
sealed ESD protective bag, all die must be stored in a dry
nitrogen environment.
WIRE BONDING
RF bonds made with 3 mil × 0.5 mil gold ribbon are recom-
mended for the RF ports. These bonds must be thermosonically
bonded with a force of 40 g to 60 g. DC bonds of 1 mil
(0.025 mm) diameter, thermosonically bonded, are recommended.
Create ball bonds with a force of 40 g to 50 g and wedge bonds
with a force of 18 g to 22 g. Create all bonds with a nominal
stage temperature of 150°C. Apply a minimum amount of
ultrasonic energy to achieve reliable bonds. Keep all bonds as
short as possible, less than 12 mil (0.31 mm).
Cleanliness
Handle the chips in a clean environment. Never use liquid
cleaning systems to clean the chip.
Static Sensitivity
Follow ESD precautions to protect against ESD strikes.
