The AD9353 is a fully integrated 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 and requiring only a balun as external component.
Key features include a 3.3‑3.8 GHz frequency range, 3.5 MHz < BW < 20 MHz bandwidth, 12‑bit ADC, 10‑bit DAC, autonomous AGC, Tx power control up to 58 dB, 8 Hz LO step size and low phase noise (< 0.8° rms). The device is powered from a single 3.3 V supply and packaged in a 9 mm × 9 mm, 64‑lead LFCSP.
