General Description

The MAX2850 is a single-chip, 4-channel RF transmitter

IC designed for 5GHz wireless HDMI applications. The

IC includes all circuitry required to implement the com-

plete 4-channel MIMO RF transmitter function and crystal

oscillator, providing a fully integrated transmit path, VCO,

frequency synthesis, and baseband/control interface.

It includes a fast-settling, sigma-delta RF fractional

synthesizer with 76Hz frequency programming step

size. The IC also integrates on-chip I/Q amplitude and

phase-error calibration circuits. Dynamic on/off control

of four external PAs is implemented with programmable

precision voltages. A 4-to-1 analog mux routes external

PA power-detect voltages to the RSSI pin.

On-chip monolithic filters are included for transmitter I/Q

baseband signal reconstruction to support both 20MHz

and 40MHz RF channels. The baseband filtering and

Tx signal paths are optimized to meet stringent WHDI

requirements. The upconverter local oscillator is coherent

among all the transmitter channels.

The reverse-link control channel uses an on-chip 5GHz

OFDM receiver. It shares the RF synthesizer and LO gen-

eration circuit with the MIMO transmitters. The receiver

includes both an in-channel RSSI and an RF RSSI.

The MIMO transmitter chip is housed in a small, 68-pin

thin QFN leadless plastic package with exposed pad.
