Description

The Celeritek CMM2308 is a high dynamic range,

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 pack-

age, the CMM2308 will drop into existing designs and offers

improved features and performance.
