Abstract

PURPOSE:To make easy the airtight processing of case and to increase the productivity, by cnstituting a coupling circuit with strip lines provided to a dielectric substrate. CONSTITUTION:A coupling circuit 6 is constituted on a dielectric substrate 7 with a Y-branch formed with strip lines 10, 11, and the electric line length of an arm 8 for Y-branch is determined so that the impedance viewing one of transmission and reception BPF's 1, 2 from the cross point of Y-branch is an open impedance mutually in the center frequency through another BPF. Further, a strip piece 16 provided in parallel with an arm 8 is connected to the arm 8 as required, and the case for the circuit is separately provided from those for transmission BPF1 and reception BPF2, and the connection between the coupling circuit 6 and BPF's 1, 2 is made via an airtight terminal 12 provided at BPF sides.
