CGA-6618 Datasheet, PDF (1/8 Pages) Stanford Microdevices – DUAL CATV BROADBAND HIGH LINEARITY GAAS HBT AMPLIFIER

CGA-6618
Product Description
Sirenza Microdevice’s CGA-6618 is a high performance GaAs
HBT MMIC Amplifier. Designed with the InGaP process technol-
ogy for excellent reliability. A Darlington configuration is utilized
for broadband performance. The heterojunction increases
breakdown voltage and minimizes leakage current between
junctions. The CGA-6618 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.
