QPA4563A中文资料DC - 3500 MHz Cascadable SiGe HBT MMIC Amplifier数据手册Qorvo规格书

描述 Description

The QPA4563A 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.
The QPA4563A may be operated from a variety of supply voltages by using a voltage dropping resistor. Two DC-blocking capacitors, bypass capacitors and an optional RF choke complete the circuit required for operation of this internally matched 50 ohm device.
The QPA4563A is assembled in an industry standard SOT-363 package that is lead-free and RoHS-compliant.
