Abstract

PURPOSE:To miniaturize as well as to decrease the number of the component parts by collecting the output parts into one unit by sharing the distribution combining output part by more than two units of BPF, and also the ensure good isolation. CONSTITUTION:Input signal f1 supplied from terminal 11 passes through filter element 13 and 14 which resonate to the same frequency with f1 and then delivered to output terminal 16 through output impedance matching section 15. And the signal power toward input terminal 20 from section 15 is almost reflected by filter element 17 and 18 which resonate to frequency f2 and thus scarecely delivered to terminal 20. In the same way, input signal f2 from terminal 20 is delivered to terminal 16 via output part 15 and not to terminal 11. As a result, the isolation is very good between terminal 11 and 20, also reducing the loss due to combination extremely.
