SGA-4363 Datasheet, PDF (1/4 Pages) Stanford Microdevices – DC-2000 MHZ CASCADABLE SIGE HBT MMIC AMPLIFIER

Product Description
Stanford Microdevices’ SGA-4363 is a high performance SiGe
Heterojunction Bipolar Transistor MMIC Amplifier. A Darlington
configuration featuring 1 micron emitters provides high F_T 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.
