This thesis consists of two parts. The first part includes design and implementation of an RF tuner module for DVB-T receiver applications. The RF tuner module adopts single-conversion architecture and has a variable gain range of more than 60 dB. After improving the tracking filter characteristics, the module can achieve an image rejection of 60 dB. The second part is focused on DVB-T RF specification test for the implemented RF tuner module. This test uses the instruments accepted by DVB association to perform the standard measurement procedure. The measured sensitivity of the module is about -86 dBm, which has good ability to receive DVB-T signal in practical environment.
