Product Description
Sirenza Microdevices’ SGA-1263 is a Silicon Germanium HBT
Heterostructure Bipolar Transistor (SiGe HBT) amplifier that
offers excellent isolation and flat gain response for applica-
tions to 4 GHz.
Preliminary
SGA-1263
DC-4000 MHz Silicon Germanium
HBT Cascadeable Gain Block
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 applica-
tions covering cellular, ISM and narrowband PCS bands.

Operation of this device beyond any one of these limits may
cause permanent damage. For reliable continous operation,
the device voltage and current must not exceed the maximum
operating values specified in the table on page one.
Bias conditions should also satisfy the following expression:
IDVD < (TJ - TL) / RTH, j-l
