N2 - This paper presents the design of a highly integrated tuner suitable for analog and digital terrestrial TV applications. The necessity to fulfil specifications for analog and digital systems at the same time comes from the fact that both systems will operate at the same time during a large period. The tuner system implements an additional up-conversion stage, which allows allocation of any TV channel at IF to the terrestrial TV frequency band (47-860MHz). This way, applications of conventional tuner systems are expanded. Results based on standard test have shown that the designed tuner is able to deliver the necessary performance in terms of selectivity, <-35dB to adj. channel protection ratio, SNR of 54dB, in band spurious emissions lower than 60dBc and ΔIMD3 of 52.8dB worst case. Finally it has been also demonstrated that with a careful design of the analog components (mixers and oscillators) the restrictive specifications of the TV tuner can be fulfilled by implementing the tuner in a low cost standard technology (0.8 μm SiGe). The total power consumption of the complete tuner is around 390 mA from a 5 V power supply.
