Product Description
The SGA-2286 is a high performance SiGe HBT 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 junc-
tions. Cancellation of emitter junction non-linearities results in
higher suppression of intermodulation products. Only 2 DC-block-
ing capacitors, a bias resistor and an optional RF choke are re-
quired for operation.
