QPA4586A

    DC - 4000 MHz Cascadable SiGe HBT MMIC Amplifier

    Key Features

    • High gain: 19.9 dB at 1950 MHz
    • Cascadable 50 ohm
    • Operates from single supply
    • Low thermal resistance package

    The QPA4586A 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.
