Product Description
RFMD’s CGA-6681(Z) 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-6618(Z)
contains two amplifiers for use in wideband Push-Pull CATV amplifiers requiring
excellent second orfer performance. The second or third order non-linearities are
greatly improved in the push pull configuration.
