General Description
The HMC994 is a GaAs MMIC pHEMT Distrib-
uted Power Amplifier which operates between DC
and 32 GHz. The amplifier provides 14 dB of gain,
36 dBm output IP3 and +28 dBm of output power at
1 dB gain compression while requiring 250 mA from
a +10 V supply. The HMC994 exhibits a slightly
positive gain slope from 5 to 25 GHz, making it
ideal for EW, ECM, Radar and test equipment
applications. The HMC994 amplifier I/Os are inter-
nally matched to 50 Ohms facilitating integra-
tion into Mutli-Chip-Modules (MCMs). All data is
taken with the chip connected via two 0.025 mm
(1 mil) wire bonds of minimal length 0.31 mm (12 mils).
