The RF MxFE® combines the RF front end with mixed-signal baseband enabling an easyto-use digital interface to the baseband ASIC or FPGA. The O 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. S The direct-conversion receiver has state-of-the-art noise figure and linearity, and requires no external components with the exception of a balun. The complete RF subsystem integrates B an autonomous AGC loop and dc offset corrections, thus eliminating the need for high speed interaction with the baseband processor. The received signal strength indicator (RSSI) has over 80 dB of dynamic range with 0....
