Product Description
Sirenza Microdevice’s CGA-3318 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 heterojunction increases breakdown
voltage and minimizes leakage current between junctions. The CGA-3318
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.
