    Qorvo's TQP519021 is a high-linearity, dual-channel down-converter designed to meet the demanding performance, functionality, and cost goals of current and next generation mobile infrastructure base stations. It provides high dynamic range performance in a low profile lead-free/RoHS-compliant surface-mount leadless package that measures 6x6 mm square. This device is a fully integrated diversity mixer that includes LO switch, two stage LO drivers, high-linearity mixers, RF balun and IF amplifiers. The IF amplifiers can be set to standard current or low current mode through logic input pins. The TQP519021 also integrates power down feature controlled by separate logic pin.

    The TQP519021 is designed to provide 9 dB conversion gain, +25.5 dBm Input IP3, +11.8 dBm Input P1dB and a noise figure of 10.8 dB over the 680-920 MHz frequency range for diversity receiver applications. The TQP519021 is footprint and pin compatible with Qorvo's 1.7 - 2.2 GHz TQP569022 mixer for high band applications.
