Product Description
RFMD’s CGA-1518Z is a high performance InGaP HBT MMIC Amplifier. Designed
with InGaP process technology for excellent reliability. A Darlington configuration is
utilized for broadband performance. The heterojunction increases breakdown volt-
age and minimizes leakage current between junctions. The CGA-1518Z contains
two amplifiers for use in wideband push-pull CATV amplifiers requiring excellent
second order performance. The second and third order non-linearities are greatly
improved in the push-pull configuration.
