QPA4486A数据手册Qorvo中文资料规格书

描述 Description

The QPA4486A 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 DC-blocking capacitors, a bias resistor, and an optional RF choke are required for operation.
