Critical Components 1. Baseband SoC l tia en fid 2. RF transceiver on The BCSR200-1E is low-power, 802.16e MIMO transceiver optimized for high performance, low cost, small area, mobile WiMAX designs. The band support, flexible channel BW, low NF, high-blocker rejection, and low-peak EVM also make BCSR200-1E suitable for fixed CPE applications. The BCSR200-1E has all of the required radio circuitry integrated into a single package, including the transmitter, C two receivers, fractional-N synthesizer with VCO, and crystal oscillator. The only required external components are the RF matching, the synthesizer loop filter, crystal, a single bias resistor, and supply decoupling. Full control of ny the BCSR200-1E RFIC is handled with a single serial interface to the baseband IC. Main Features ¡band support pa — Supports 2.5 GHz to 2.695 GHz band — Single IC allows the design of a two Rx and one Tx band radio ¡Integrated channel filters with dynamically adjustable channel bandwidth (5 MHz to 20 MHz) om — External SAW no longer needed — Allows support of the 5, 7, 8.75, and 10 MHz channels ¡bandwidth as well as 5 MHz/10 MHz, 3A WiMAX band class ¡ 2.5V to 2.7V operation with very low power consumption C — 30% reduction of Rx and Tx current from previousgeneration ¡ −20ºC to 85ºC operating temperature range ¡ 7 mm x 7 mm QFN package ¡Low noise MIMO receivers ¡ Low EVM transmitter —FCC and ETSI compliant for mobile terminals in the 2.5 GHz to 2.695 GHz band ¡ Integrated synthesizer —<5 Hz frequency resolution

3. DRAM The HY5PS121621CFP-Y5-C is a 512Mb DDR2 and operating at 166.6MHz (Data rate 333MHz/b) on MAX-207HW2. 4. FALSH There are two type of FLASH on MAX-207HW2 Serial-NOR FLASH：MX25L8005 is a 8Mb SPI FLASH, it contains boot-code、WiMAX calibration files and MAC address inside.
