It has two transmitters and two receivers, with differential 100I RF inputs and outputs. The IC includes all circuitry required to implement the plete RF transceiver function, providing fully integrated receive paths, transmit path, VCO and tank, frequency synthesis, and baseband/control interface. It includes a fast-settling sigma-delta RF fractional synthesizer with ~25Hz frequency step size. The IC also integrates an on-chip AM detector for measuring transmitter I/Q imbalance and LO leakage. An internal transmit-toreceive loopback mode allows for receiver I/Q imbalance calibration. The IC supports full duplex mode of operation for external loopback. The MAX2842 pletely eliminates the need for external SAW filters by implementing on-chip programmable monolithic filters for both receiver and transmitter, for channel bandwidths from 3.5MHz to 10MHz. The baseband filtering Rx and Tx signal paths are optimized to meet stringent noise figure and linearity requirements. The transceiver is housed in a small 56-pin TQFN, 7mm x 7mm, leadless plastic package with exposed paddle. -65d B Relative Spectral Emission Mask 3.8d B Receiver Noise Figure Automatic On-Chip Receiver I/Q DC Cancellation On-Chip Tx I/Q Gain/Phase Error and LO Leakage Detection Integrated Phase Noise Rx Channel Filters for 3.5MHz, 5MHz, 7MHz, and 10MHz Channels Programmable Tx I/Q Lowpass Reconstruction Filters Fractional PLL with 50µs Channel Hopping Time (Settling to 50Hz) 4-Wire Bidirectional SPI™ Interface 60d B Transmit Power Control Range, Digitally Controlled by SPI 71d B...
