GENERAL DESCRIPTION

The AD9355 is a radio frequency (RF) transceiver with a single transmitter and dual receivers fully integrated into the device. This allows the part to be used for mobile and fixed WiMAX/WiBro wireless network systems. By incorporating an RF MxFE™, the AD9355 offers the combination of an RF front end and a mixedsignal baseband, enabling an easy-to-use JESD-207-compliant digital interface to the baseband application-specific integrated circuit (ASIC) or field-programmable gate array (FPGA). In addition, the AD9355 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, and 10 MHz are supported.
