    Key Features

    • DC to 3500 MHz Operation
    • Single positive voltage supply
    • Cascadable 50 ohm
    • High gain: 19.2 dB at 1950 MHz
    • Output IP3: +31.9 dBm typical at 1950 MHz
    • Noise figure: 3.4 dB typical at 1950 MHz
    • Robust 1000 V class 1C HBM ESD rating
    • Low thermal resistance SOT-89 package
    • Lead-free / RoHS-Compliant

    The QPA6489A 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 QPA6489A 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 QPA6489A is assembled in an industry standard SOT-89 package that is lead-free and RoHS-compliant.

    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.
