The direct conversion QPSK demodulator is the front-end receiver dedicated to digital TV broadcasting, satisfying both DVB-S and DBS TV standards. The wide range oscillator (from 950 MHz to 2175 MHz) covers the American, European and Asian satellite bands, as well as the SMA-TV US standard. The Zero-IF (ZIF) concept discards traditional IF filtering and inter.
