Description
The unconditional stability and internal matching
provides for reduction of external components making this
product a simple and low-cost solution. The package is
designed with a base material of gold-plated copper/molybde-
num composite that offers excellent thermal properties and
minimum mechanical stress.
The CMM1331-KU is a four-stage pHEMT GaAs
MMIC power amplifier that is ideally suited for transmit
subsystems designed for Ku-Band VSAT applications. The
CMM1331-KU provides 32.0 dB linear gain and delivers
1.5 watts of output power at saturation operating from
12.70 to 13.50 GHz frequency.
