General Description
The HMC-APH478 is a two stage GaAs HEMT MMIC
1 Watt Power Amplifier which operates between 18
and 20 GHz. The HMC-APH478 provides 17.5 dB
of gain, and an output power of +30 dBm at 1 dB
compression from a +5V supply voltage. All bond
pads and the die backside are Ti/Au metallized and
the amplifier device is fully passivated for reliable
operation. The HMC-APH478 GaAs HEMT MMIC
1 Watt Power Amplifier is compatible with conventional
die attach methods, as well as thermocompression
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.
