A fully integrated low-IF DVB-T receiver architecture

Abstract

We propose a fully integrated DVB-T receiver architecture for low cost CMOS implementation. The receiver uses a dual-IF architecture to cover the receive bands from 170 MHz to 862 MHz and a low-IF of 4.57 MHz. Key performance values meet the DVB-T requirements with competitive performance (sensitivity 72.5 dBm, noise figure 6.6 dB, adjacent channel protection ratio (ACPR)= -43 dB, available SNR=28 dB) and suggest that low cost receivers are realistic in volume for the coming digital broadcasting systems.
