Datasheet SGA-1263 Datasheet (Stanford Microdevices)

Product Description

Stanford Microdevices’ SGA-1263 is a Silicon Germanium
HBT Heterostructure Bipolar Transistor (SiGe HBT) amplifier
that offers excellent isolation and flat gain response for
applications to 4 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 FT 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 applica­tions covering cellular, ISM and narrowband PCS bands.
