Preliminary QPA4463A RFMD + TriQuint = Qorvo DC to 3500MHz, CASCADABLE SiGe HBT MMIC AMPLIFIER The QPA4463A 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 opt
