19-4588; Rev 1; 5/10 KIT ATION EVALU E L B AVAILA 2.3GHz to 2.7GHz MIMO Wireless Broadband RF Transceiver The MAX2839AS direct conversion, zero-IF, RF transceiver is designed specifically for 2.3GHz to 2.7GHz 802.16e MIMO mobile WiMAXTM systems. The device incorporates one transmitter and two receivers, with > 40dB isolation between each receiver. The MAX2839AS completely integrates all circuitry required to implement the RF transceiver function, providing RF to baseband receive path, and baseband to RF transmit path, VCO, frequency synthesizer, crystal oscillator, and baseband/control interface. The device includes a fast-settling sigma-delta RF synthesizer with smaller than 40Hz frequency steps and a crystal oscillator that allows the use of a low-cost crystal in place of a TCXO. The transceiver IC also integrates circuits for on-chip DC-offset cancellation, I/Q error, and carrier leakage detection circuits. An internal transmit to receive loopback mode allows for receiver I/Q imbalance calibration. The local oscillator I/Q quadrature phase error can be digitally corrected in approximately 0.125 steps. Only an RF bandpass filter (BPF), crystal, RF switch, PA, and a small number of passive components are needed to form a complete wireless broadband RF radio solution. The MAX2839AS completely eliminates the need for an external SAW filter by implementing on-chip programmable monolithic filters for both the receiver and transmitter, for all 2GHz and 802.16e profiles and WiBro. The baseband filters along with the Rx and Tx signal paths are optimized to meet the stringent noise figure and linearity specifications. The device supports up to 2048 FFT OFDM and implements programmable channel filters for 3.5MHz to 20MHz RF channel bandwidths. The transceiver requires only 2s Tx-Rx switching time. The IC is available in a small wafer-level package (WLP) measuring 5.16mm x 3.66mm x 0.5mm.

See Table 1 for a summary of the modes of operation. When the parts are active, various blocks can be shutdown individually by programming different SPI registers. Shutdown Mode The MAX2839AS features a low-power shutdown mode. In shutdown mode, all circuit blocks are powered down, except the 4-wire serial bus and its internal programmable registers. Clock-Out Only In clock-out mode, the entire transceiver is off except the divided reference clock output on the CLKOUT pin and the clock divider, which remain on. Standby Mode The standby mode is used to enable the frequency synthesizer block while the rest of the device is powered down. In this mode, the PLL, VCO, and LO gener- ator are on so that Tx or Rx modes can be quickly enabled from this mode. These and other blocks can be selectively enabled in this mode by programming different SPI registers. Receive (Rx) Mode In receive mode, all Rx circuit blocks are powered on and active. Antenna signal is applied; RF is downconverted, filtered, and buffered at Rx BB I and Q outputs. Either receiver A or both receivers can be enabled. Receiver B cannot be enabled by itself. Transmit (Tx) Mode In transmit mode, all Tx circuit blocks are powered on. The external PA is powered on after a programmable delay using the on-chip PA bias DAC. Transmitter (Tx) Calibration Mode All Tx circuit blocks except PA driver and external PA are powered on and active. The AM detector and receiver I/Q channel buffers are also on, along with multiplexers in the receiver side to route this AM detector's signal to each I and Q differential outputs. When required, the I/Q lowpass filter can be bypassed. ______________________________________________________________________________________ 21 MAX2839AS Table 1. Operating Mode MAX2839AS 2.3GHz to 2.7GHz MIMO Wireless Broadband RF Transceiver Receiver (Rx) Calibration or Loopback Part of the Rx and Tx circuit blocks except LNA and PA driver are powered on and active. The transmitter I/Q input signals are upconverted to RF, and the output of the Tx gain control block (VGA) is fed to the receiver at the input of the downconverter. Either receiver A or both receivers can be connected to the transmitter and powered on. The I/Q lowpass filters are not present in the transmitter signal path (they are bypassed). 10 least significant bits (LSBs) are register data. Register data is loaded through the 4-wire SPI/MICROWIRETM-compatible serial interface. Data at DIN is shifted in MSB first and is framed by CS. When CS is low, the clock is active, and input data is shifted at the rising edge of the clock. During the read mode, register data selected by address bits is shifted out to DOUT at the falling edges of the clock. At the CS rising edge, the 10-bit data bits are latched into the register selected by address bits. See Figure 1. The register values are preserved in shutdown mode as long as the power-supply voltage is maintained. After power-up, the user must program all register values. Programmable Registers and 4-Wire SPI Interface The MAX2839AS includes 32 programmable 16-bit registers. The most significant bit (MSB) is the read/write selection bit. The next 5 bits are register address.
