Product Description
SGA-4363
Stanford MicrodevicesSGA-4363 is a high performance SiGe
HeterojunctionBipolarTransistorMMICAmplifier# ADarlington
configuration featuring 1 micron emitters provides high FT and
excellent thermal perfomance# The heterojunction increases
breakdown voltage and minimizes leakage current between
junctions# Cancellation of emitter junction non-linearities results
in higher suppression of intermodulation products# At 850 Mhz
and 45mA , the SGA-4363 typically provides +28#7 dBm output
IP3, 16#4 dB of gain, and +14#3 dBm of 1dB compressed power
using a single positive voltage supply# Only 2 DC-blocking
capacitors, a bias resistor and an optional RF choke are required
for operation#
