Product Description
RFMD’s CXE-1089Z is a high performance 75Ω pHEMT MMIC low-noise
amplifier utilizing a Darlington configuration with active bias. The active
bias network provides stable current over temperature and process
threshold voltage variations. The CXE-1089Z amplifier is designed for high
linearity, low-noise consumer set-top box applications. It is internally
matched to 75Ω and operates directly from 5V.
