CGA-3318 Datasheet, PDF (1/8 Pages) Stanford Microdevices – Dual CATV Broadband High Linearity SiGe HBT Amplifier

CGA-3318
Product Description
CGA-3318Z
Pb RoHS Compliant
& Green Package
Sirenza Microdevice’s CGA-3318 is a high performance Silicon Germanium
HBT MMIC Amplifier. Designed with SiGe process technology for excellent
Dual CATV Broadband High Linearity SiGe
linearity at an exceptional price. A Darlington configuration is utilized for HBT Amplifier
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.
