摘要: A frequency tunable filter (110) and an associated apparatus (100) are provided, where the may include a plurality of ports (IN, OUT) including input port (IN) output (OUT), further inductor-capacitor (LC) resonator (110R), switching unit (110S) that is coupled between LC (110R) ground terminal (110), resonance adjustment (110LC, L2, C2) terminal. For example, first to each second terminal, selectively provide conduction path change characteristic (110R).
