Abstract:
1. A method for manufacturing a TV tuner, wherein the TV tuner having a Very High Frequency (VHF) tracking filter, a VHF matching circuit and a single conversion Tuner IC, the method is characterized in that: using Low-Temperature Co-fired Ceramics (LTCC) inductors in the VHF tracking filter and the VHF matching circuit to determine a maximum gain frequency; tuning the single conversion Tuner IC for 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 VHF tracking filter and VHF matching circuit respectively; and tuning a fine-tune capacitor of the VHF tracking filter and the LTCC inductor of the VHF matching circuit to determine the maximum gain frequency of the VHF tracking filter and the VHF matching circuit.
