Ordering Information
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 crys-
tal oscillator, providing a fully integrated transmit path,
VCO, frequency synthesis, and baseband/control inter-
face. 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 coher-
ent 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.
