    摘要： An antenna switching circuit which selectively transmits, to a receiver, RF signals from a plurality of antennas including RF signals of different frequency bands such as the VHF band and the MF band using a single output terminal. To prevent a level drop of RF signals of one of the frequency bands due to a common use of the output terminal, a unidirectional switching element is added to a switching circuit network by which the selection of RF signals from the different antennas is performed.A branching circuit for separating RF signals of different frequency bands is provided with an attenuation operation using a variable impedance characteristic of a semiconductor switching element which is basically on-off operated for the switching between the RF signals of the different frequency bands.
