Abstract

PURPOSE:To decrease the number of component parts of the equipment and reduce the production cost, by providing one filter on the high frequency input circuit, and executing the branching of a signal of two different frequency bands. CONSTITUTION:The low-pass filter circuit consisting of a coil 22, a capacitor 23 and a coil 24 sets its cut-off frequency so that it is higher than that of a VHF band signal and also lower than that of a UHF band signal, and in addition, sets the resonance frequency of a series circuit consisting of a coil 22 and a capacitor 23 so that it is lower than that of a UHF band signal. And, when a high frequency signal which is input is a VHF band signal, the VHF signal is output to the terminal 26, and on the other hand, when a high frequency signal which is input is a UHF band signal, the UHF signal is output to the terminal 27.
