QPA5389A

    DC - 4500 MHz Cascadable SiGe HBT Amplifier

    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.

    X-Microwave Design System

    This product is available as an X-Microwave Block (X-MWblock) for evaluation.

    X-MWblocks are RF and microwave "drop-in" components that can be used individually for prototyping or in production assemblies. X-MWblocks are easy to test, integrate, align, and configure to 60 GHz and beyond. No messy sweat soldering or silver epoxy processes are required. X-MWblocks are highly characterized with S-parameter models and connect with a patented solder-less interconnect technology.
