Product Description

RFMD’s CGA-6681Z is a high performance GaAs HBT MMIC amplifier. Designed

with the InGaP process technology for excellent reliability. A Darlington configura-

tion is utilized for broadband performance. The heterojunction increases break-

down voltage and minimizes leakage current between junctions. The CGA-6618Z

contains two amplifiers for use in wideband push-pull CATV amplifiers requiring

excellent second order performance. The second or third order non-linearities are

greatly improved in the push pull configuration.
