Product Description
Features
RFMD’s CGA-7718Z is a high performance InGaP HBT MMIC Amplifier. Designed  5 V Single Supply
with the InGaP process technology for excellent reliability. A Darlington configura-
tion is utilized for broadband performance. The heterojunction increases break-
 Excellent Linearity Perfor-
mance at +34dBmV Output
down voltage and minimizes leakage current between junctions. The CGA-7718Z
contains two amplifiers for use in wideband push-pull CATV amplifiers requiring
excellent second order performance. The second and third order non-linearities are
S greatly improved in the push-pull configuration.
