  • The STMicroelectronics STW82101B is an integrated down converter providing 8.5 dB of gain, 9.5 dB NF, and a very high input linearity by means of its passive mixer.

    Embedding two wide band auto calibrating VCOs and an integer-N synthesizer, the STW82101B is suitable for both Rx and Tx requirements for Cellular infrastructure equipment.
    The integrated RF balun and internal matching permit direct 50 ohm single-ended interface to RF port. The IF output is suitable for driving 200-ohm impedance filters.
    By embedding a DAC with dual current output to drive an external PIN diode attenuator, the STW82101B replaces several costly discrete components and offers a significant footprint reduction.
    The STW82101B device is designed with STMicroelectronics advanced 0.35 μm SiGe process. Its performance is specified over a -40 °C to +85 °C temperature range.
