Description
The CMM1430-KU is a four-stage pHEMT GaAs
MMIC power amplifier that is ideally suited for transmit sub-
systems designed for Ku-Band VSAT applications. The
CMM1430-KU provides 34.5 dB linear gain and delivers 1.5
watts of output power at saturation operating from 13.75 to
14.5 GHz frequency.
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.
