Abstract :
A zero-IF Tuner IC with wide RF input range (92dB) and low power consumption (528mW in a single 3.3V supply) for full-segment ISDB-T Digital reception was realized using 0.25µm RF-CMOS technology. Instead of external SAW filters, 10th-order baseband filters were implemented. The wideband receiver selects one of two LNAs in condition of full-segment ISDB-T 64QAM modulation (CR=3/4) and provides either low-IF or direct-IF.
