Abstract:
1. A cellular telephone set capable of receiving a plurality of broadcast waves, comprising: an antenna for sending and receiving a radio wave in a band used by the cellular telephone set and receiving a plurality of broadcast waves; a first switch; a cellular telephone set radio unit for performing a cellular telephone function using said antenna; a radio unit selector switch branching a line connected to said antenna into two lines that are connected respectively to said first switch and said cellular telephone set radio unit; a second switch; a plurality of impedance adjusting circuits connected in parallel between said first switch and said second switch and associated with said plurality of broadcast waves, respectively; a TV/FM controller for outputting an identification signal representing one of the broadcast waves, that is being currently received to said first switch and said second switch; and a TV/FM receiver for demodulating the broadcast wave which is output from said second switch; wherein said first switch and said second switch select one of said impedance adjusting circuits which is associated with the broadcast wave that is being currently received and which is represented by said identification signal.
