EVALUATION KIT AVAILABLE  
MAX2851  
5GHz, 5-Channel MIMO Receiver  
General Description  
Features  
The MAX2851 is a single-chip, 5-channel RF receiver IC  
designed for 5GHz wireless HDMI™ applications. The  
IC includes all circuitry required to implement the com-  
plete 5-channel MIMO RF receiver function and crystal  
oscillator, providing a fully integrated receive path, VCO,  
frequency synthesis, and baseband/control interface. It  
includes a fast-settling sigma-delta RF fractional synthe-  
sizer 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 also an RF RSSI.  
● 5GHz, 5x MIMO Downlink Receivers, Single-Uplink  
IEEE 802.11a Transmitter  
● 4900MHz to 5900MHz Frequency Range  
● Coherent LO Among Receivers  
● 4.5dB Rx Noise Figure  
● 70dB Rx Gain Control Range with 2dB Step Size,  
Digitally Controlled  
● 60dB Dynamic Range Receiver RSSI  
● RF Wideband Receiver RSSI  
● Programmable 20MHz/40MHz Rx I/Q Lowpass  
On-chip monolithic filters are included for receiver I/Q  
baseband signal channel selection, for supporting both  
20MHz and 40MHz RF channels. The baseband filtering  
and Rx signal paths are optimized to meet stringent WHDI  
requirements. The downconverter local oscillator is coher-  
ent among all the receiver channels.  
Channel Filters  
● -5dBm Transmit Power (54Mbps OFDM)  
● 31dB Tx Gain Control Range with 0.5dB Step Size,  
Digitally Controlled  
● Tx/Rx I/Q Error and LO Leakage Detection and  
The reverse-link control channel uses an on-chip 5GHz  
OFDM transmitter. It shares the RF synthesizer and LO  
generation circuit with the MIMO receivers. Dynamic  
on/off control of the external PA is implemented with  
programmable precision voltage. An analog mux routes  
external PA power-detect voltage to the RSSI pin.  
Adjustment  
● Programmable 20MHz/40MHz Tx I/Q Lowpass  
Anti-Aliasing Filter  
● Analog Mux for PA Power Detect  
● PA On/Off Control  
The MIMO receiver chip is housed in a small 68-pin TQFN  
leadless plastic package with exposed paddle.  
● Sigma-Delta Fractional-N PLL with 76Hz Resolution  
● Monolithic Low-Noise VCO with -35dBc Integrated  
Phase Noise  
Applications  
● 4-Wire SPI Digital Interface  
● 5GHz Wireless HDMI (WHDI™)  
● 5GHz FDD Backhaul and WiMAX™  
● 5GHz MIMO Receiver Up to Five Spatial Streams  
● 5GHz Beam Steering Receiver  
● I/Q Analog Baseband Interface  
● Digital Tx/Rx Mode Control  
● On-Chip Digital Temperature Sensor Readout  
● Complete Baseband Interface  
● Digital Tx/Rx Mode Control  
● +2.7V to +3.6V Supply Voltage  
● Small 68-Pin TQFN Package (10mm x 10mm)
