GENERAL DESCRIPTION

The AD9353 is a fully integrated transceiver for IEEE 802.16 WiMAX wireless network systems. The RF MxFE® combines the RF front end with mixed-signal baseband enabling an easy-to-use digital interface to the baseband ASIC or FPGA. The AD9353 operates in the 3.3 GHz to 3.8 GHz range covering most of the licensed and unlicensed bands. Channel bandwidths of 3.5 MHz, 4.375 MHz, 5 MHz, 7 MHz, 8.75 MHz, 10 MHz, 14 MHz, 17.5 MHz, and 20 MHz are supported.
