The MAX2842 is a single‑chip, direct‑conversion, zero‑IF RF transceiver IC designed for 3 GHz non‑line‑of‑sight MIMO systems. It integrates two transmitters and two receivers, on‑chip VCO, programmable filters, and a 4‑wire SPI interface in a compact 56‑pin TQFN package.
Key specifications include a 3.3‑3.9 GHz RF range, 60 dB gain control, 0 dBm maximum output power, 3.8 dB noise figure, and programmable channel bandwidths from 3.5 MHz to 10 MHz. The device operates from 2.7 V to 3.6 V and supports full‑duplex operation with digital control of gain, shutdown, and standby modes.
