Adjacent channel rejection in double conversion tuner |
摘要 |
A double conversion tuner includes a first filter that is relatively flat over a 6 MHz band at 920 MHz. A pair of series-parallel resonant circuits form notch filters that operate on the downconverted signals to economically produce a 6 MHz frequency response at 44 MHz that has excellent adjacent channel and other signal rejection.
