Abstract
PURPOSE:To provide a band width to a trap and to reduce the change in characteristics depending on the temperature, by constituting each trap circuit to have different position and size of the 1st and 2nd stage traps. CONSTITUTION:In a local oscillation trap circuit 5, the position of copper foil constituting the 1st stage trap 5a and the 2nd stage trap 5b is shifted and the size of the traps 5a and 5b is made different that the sizes 15 and 17 of the trap 51 are shorter than those 14 and 18 of the trap 5b. As a result, +50 MHz can be set with the trap 5a and -50MHz can be set with the trap 5b. On the other hand, as to a trap circuit 6 of an image signal, the position of copper foil constituting the trap 6a of the 1st stage and the trap 6b of the 2nd stage is changed mutually and the size of the traps 6a and 6b is changed for the 21 and 24 of the trap 6a from the 22 and 23 of the trap 6b. Thus, the band width of image frequency can be set to 108 MHz.
