Functional Diagram
General Description
The HMC-APH634 is a two stage GaAs HEMT MMIC
Medium Power Amplifier which operates between
81 and 86 GHz. The HMC-APH634 provides 12
dB of gain, and an output power of up to +20 dBm
at 1 dB compression from a +4V supply. All bond
pads and the die backside are Ti/Au metallized
and the amplifier device is fully passivated for reliable
operation. The HMC-APH634 GaAs HEMT MMIC
Medium Power Amplifier is compatible with conven-
tional die attach methods, as well as thermocomp-
ression and thermosonic wire bonding, making it
ideal for MCM and hybrid microcircuit applications.
All data shown herein is measured with the chip in
a 50 Ohm environment and contacted with RF probes.
