The CMD244 is wideband GaAs MMIC

distributed amplifier die which operates from DC

to 24 GHz. The amplifier delivers 18 dB of gain

with a corresponding output 1 dB compression

point of +25 dBm and noise figure of 2.5 dB at

10 GHz. The CMD244 is a 50 ohm matched

design which eliminates the need for RF port

matching. The CMD244 offers full passivation

for increased reliability and moisture protection.

This amplifier is the perfect alternative to higher

cost hybrid amplifiers.

► Ultra wideband performance

► Positive gain slope

► High output power

► Low noise figure

► Small die size
