BROADBAND DISTRIBUTED AMPLIFIER
ADM-0040M
The ADM-0040M is a broadband, efficient GaAs PHEMT
distributed amplifier. It can be operated with a single positive
bias, or with a negative bias voltage to achieve 12 dB typical
gain and 22 dBm typical output power at 1 dB compression
for only 160 mA of current. Applications include mixer LO
amplification, electronic warfare, test and measurement, and
amplification of optical modulator signals. It is an excellent
alternative to competing GaAs PHEMT distributed amplifiers.
