Description

The Celeritek CMM2308 is a high dynamic range,
pin-compatible, second source for the TriQuint®9132 and the
Mini-Circuits®VNA. Providing comparable gain and lower
noise figure than either of the existing standard amplifiers at

25% less drain current, the CMM2308 is an excellent choice
for power sensitive applications, while delivering more design
margin. Packaged in a low-cost surface mount SOIC-8 pack­age, the CMM2308 will drop into existing designs and offers
improved features and performance.
