General Description
The HMC797 is a GaAs MMIC PHEMT Distributed
Power Amplifier die which operates between DC
and 22 GHz. The amplifier provides 14.5 dB of gain,
40 dBm output IP3 and +28 dBm of output power at
1 dB gain compression while requiring 400mA from
a +10V supply. This versatile PA exhibits a posi-
tive gain slope from 3 to 21 GHz making it ideal for
EW, ECM, Radar and test equipment applications.
The HMC797 amplifier I/Os are internally matched
to 50 Ohms facilitating integration into Mutli-Chip-
Modules (MCMs). All data is taken with the chip
connected via two 0.025mm (1 mil) wire bonds of mini-
mal length 0.31 mm (12 mils).
