QPA4263A
DC to 3500MHz, CASCADABLE SiGe HBT MMIC AMPLIFIER
The QPA4263A is a high performance SiGe HBT MMIC amplifier. A Darlington configuration provides high FT and excellent thermal performance. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. Cancellation of emitter junction non-linearities results in higher suppression of intermodulation products. Only two DCblocking capacitors, a bias resistor, and an optional RF choke are required for operation.
