Product Description
SGA-1163
Sirenza Microdevices SGA-1163 is a Silicon Germanium HBT
Heterostructure Bipolar Transistor (SiGe HBT) amplifier that
offers excellent isolation and flat gain response for applica-
tions to 6 GHz.
This RFIC is a 2-stage design that provides high isolation of
up to 40dB at 2 GHz and is fabricated using the latest SiGe
HBT 50 GHz F
T
process, featuring 1 micron emitters with
Vceo > 7V.
These unconditionally stable amplifiers have less than 1dB
gain drift over 125ºC operating range (-40C to +85C) and
are ideal for use as buffer amplifiers in oscillator applica-
tions covering cellular, ISM and narrowband PCS bands.
