DC-4500 MHz SiGe HBT Amplifier

Part # QPA5389A


Key Features

  • High gain: 15.9 dB at 1950 MHz
  • Cascadable 50 ohm
  • Operates from single supply
  • Low thermal resistance package


The QPA5389A 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.
