The AD9353 is a fully integrated WiMAX RF MxFE transceiver that integrates ADCs and DACs, operates in the 3.3 to 3.8 GHz band, and has a bandwidth of 3.5 to 20 MHz. The AD9353 has a low noise figure of 3.2 dB and a highly linear and spectrally pure transmitter.
The AD9353 is a fully integrated RF transceiver for IEEE 802.16 WiMAX systems. It combines the RF front‑end with mixed‑signal baseband, providing a digital interface to a baseband ASIC or FPGA. The device operates from 3.3 GHz to 3.8 GHz and supports channel bandwidths from 3.5 MHz up to 20 MHz. Features include a 12‑bit ADC, 10‑bit DAC, autonomous AGC, Tx power control, and an internal fractional‑N synthesizer with 8 Hz LO steps.
The transceiver is powered from a single 3.3 V supply and includes on‑chip LDOs, eliminating external regulators. It is packaged in a 9 mm × 9 mm, 64‑lead LFCSP. An internal auxiliary ADC and two DACs are available for system monitoring, and three general‑purpose I/Os can be programmed via a 4‑wire serial port.
