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 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.

2. We recommend 1 or 2 ounce copper. Measurements
for this data sheet were made on a 31 mil thick FR-4
board with 1 ounce copper on both sides.
