Preliminary SGA-1263 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 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 125C operating range (-40C to +85C) and are ideal for use as buffer amplifiers in oscillator applications covering cellular, ISM and narrowband PCS bands.
