Abstract:
1. A method for manufacturing a TV tuner, wherein the TV tuner having an Ultra High Frequency (UHF) tracking filter, a UHF matching circuit and a single conversion Tuner IC, the method is characterized in that: using Low-Temperature Co-fired Ceramics (LTCC) inductors in the UHF tracking filter and the UHF matching circuit to determine a maximum gain frequency; tuning the single conversion Tuner IC to obtain a tuned-voltage, wherein the tuned-voltage is used to determine the capacitances of a first varactor diode and a second varactor diode of the UHF tracking filter and UHF matching circuit respectively; and tuning the capacitance of a fine-tune capacitor of the UHF tracking filter and the inductance of the LTCC inductor of the UHF matching circuit to determine the maximum gain frequency of the UHF tracking filter and the UHF matching circuit.
