DC to 20 GHz Distributed Amplifier Offers Low Noise Figure of 2 dB at 10 GHz

The CMD173P4 is a GaAs MMIC distributed amplifier operating from DC to 20 GHz that delivers greater than 15 dB of gain with a corresponding output of 1 dB compression point of +18 dBm and noise figure of 2 dB at 10 GHz. Housed in a leadless 4 x 4 mm plastic surface mount package, the CMD173P4 also utilizes an on-chip pinch off tracking circuit to ensure consistent performance over temperature and process variation. The CMD173P4 is a 50 Ohm matched design that requires some off-chip components to complete the bias network, which is typical of this amplifier topology.

Suitable applications for the CMD173P4 include microwave radio systems, telecom infrastructure, test instrumentation, and military EW subsystems.
