Product Description
RFMD’s SGA1263Z is a Silicon Germanium HBT Heterostructure Bipolar
Transistor (SiGe HBT) amplifier that offers excellent isolation and flat gain
response for application to 4GHz. This RFIC is a 2-stage design that pro-
vides high isolation of up to 40dB at 2GHz and is fabricated using the lat-
est SiGe HBT 50GHz F_T process, featuring one-micron emitters with
V_CEO>7V. These unconditionally stable amplifiers have less than 1dB gain
drift over 125°C operating range (-40°C to +85°C) and are ideal for use
as buffer amplifiers in oscillator applications covering
Optimum Technology _{cellular, ISM, and narrowband PCS bands.}
