HMC395
InGaP HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 4 GHz
V02.0109
General Description
Features
Functional Diagram
The HMC395 die is a GaAs InGaP Heterojunction Bi-
polar Transistor (HBT) Gain Block MMIC DC - 4 GHz
ampli er. This ampli er die can be used as either a
cascadable 50 Ohm gain stage or to drive the LO of
HMC mixers with up to +17 dBm output power. The
HMC395 offers 16 dB of gain and an output IP3 of +31
dBm while requiring only 54 mA from a +5V supply.
The Darlington feedback pair used results in reduced
sensitivity to normal process variations and yields ex-
cellent gain stability over temperature while requiring
a minimal number of external bias components. The
HMC395 can easily be integrated into Multi-Chip-
Modules (MCMs) due to its small (0.22mm2) size. All
data is with the chip in a 50 Ohm test xture connected
via 0.025mm (1mil) diameter wire bonds of minimal
length 0.5mm (20mils).
Gain: 15 dB

Assembly Diagram
Handling Precautions
Follow these precautions to avoid permanent damage.
Storage: All bare die are placed in either Waffle or Gel based ESD protective containers, and then sealed in an ESD protective bag
for shipment. Once the sealed ESD protective bag has been opened, all die should be stored in a dry nitrogen environment.
Cleanliness: Handle the chips in a clean environment. DO NOT attempt to clean the chip using liquid cleaning systems.
Static Sensitivity: Follow ESD precautions to protect against ESD strikes.
Transients: Suppress instrument and bias supply transients while bias is applied. Use shielded signal and bias cables to minimize
inductive pick-up.
General Handling: Handle the chip along the edges with a vacuum collet or with a sharp pair of bent tweezers. The surface of the
chip has fragile air bridges and should not be touched with vacuum collet, tweezers, or ngers.
Mounting
The chip is back-metallized and can be die mounted with AuSn eutectic preforms or with electrically conductive epoxy. The
mounting surface should be clean and at.
Epoxy Die Attach: Apply a minimum amount of epoxy to the mounting surface so that a thin epoxy llet is observed around the
perimeter of the chip once it is placed into position. Cure epoxy per the manufacturer’s schedule.
Wire Bonding
Ball or wedge bond with 0.025mm (1 mil) diameter pure gold wire. Thermosonic wirebonding with a nominal stage temperature of
150 deg. 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 <0.31mm (12 mils).
