Product Description
RFMD’s CGA-3318Z is a high performance Silicon Germanium HBT MMIC Amplifier.
Designed with SiGe process technology for excellent linearity at an exceptional
price. A Darlington configuration is utilized for broadband performance. The hetero-
junction increases breakdown voltage and minimizes leakage current between
junctions. The CGA-3318Z 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.
