摘要：

This paper proposed a scheme of direct down-conversion which realize a radio frequency (RF) front end of Zero-IF receiver based on DMB-TH (Digital Multimedia Broadcast-Terrestrial/Handheld). It was materialized by FC2558 tuner IC and EPM570 controller. Besides, tests and analysis about the filter and the automatic gain controller (AGC) of this system are illustrated in detail. The system shows excellent performance on anti-interferences and has several features including simple circuit structure, low power consumption, low noise figure and wide input dynamic range.
