ADL5802

Data Sheet FEATURES Power conversion gain of 1.6 dB Wideband RF, LO, and IF ports SSB noise figure of 11 dB Input IP3 of 28 dBm Input P1dB of 12 dBm Typical LO drive of 0 dBm Low LO leakage Single supply operation: 5 V @ 240 mA Exposed paddle, 4 mm × 4 mm, 24-lead LFCSP package APPLICATIONS Cellular base station receivers Main and diversity receiver designs Radio link downconverters GENERAL DESCRIPTION The ADL5802 uses high linearity, double-balanced, active mixer cores with integrated LO buffer amplifiers to provide high dynamic range frequency conversion from 100 MHz to 6 GHz. The mixers benefit from a proprietary linearization architecture that provides enhanced input IP3 performance when subject to high input levels. A bias adjust feature allows the input linearity, SSB noise figure, and dc current to be optimized using a single control pin. The high input linearity allows the device to be used in demanding cellular applications where in-band blocking signals may otherwise result in degradation in dynamic performance. The balanced active mixer arrangement provides superb LO to RF and LO to IF leakage, typically better than −30 dBm.
