Additional Details

The MAX2852 is a single-chip RF receiver IC designed for 5GHz wireless applications. The IC includes all circuitry required to implement a complete receiver-crystal oscillator, VCO, PLL, LNA, VGA, and baseband filters. It includes a fast-settling, sigma-delta fractional synthesizer with 76Hz frequency programming step size. The IC also integrates on-chip I/Q amplitude and phase-error calibration circuits. The receiver includes both an in-channel RSSI and an RF RSSI.

The receiver chip is housed in a small, 68-pin thin QFN leadless plastic package with exposed pad.
