Abstract
PURPOSE: To realize application to a plane-wired tuner by adjusting an inductance by providing a slidable metal piece between two resonance coils.
CONSTITUTION: Two resonance coils 15 and 16 are arranged in parallel; one-side terminals of both coils 15 and 16 are mutually connected and further connected to varactor diode 3, etc., and while the other terminal of coil 15 is grounded, the other one of coil 16 is free. In this way, metal piece 17 is inserted between resonance coils 15 and 16 to make a connection between both coils 15 and 16 and metal piece 17 is slid to make an adjustment of an inductance. Consequently, coils 15 and 16 themselves provide the inductance adjustment and an earth surface extending over a wide area is unneeded, so that application to a plane-wired tuner can be realized.
