Composite filter

Abstract

Abstract PURPOSE:To constitute a composite filter with a simple construction by mounting two filters on one surface of a printed board and connecting the input terminal of respective filters on the other surface of the printed board with a strip line. CONSTITUTION:Dielectric filters 7 and 14 are electrically connected by ground terminals 3-6 and 10-13 onto one surface to execute a ground electrode 16 of a printed board 15 and fixed mechanically by small holes 21-24 and 25-28. On the rear side of the printed board 15, input electrodes 29 and 30 and a shared electrode 35 are connected with strip lines 33 and 34 and output electrodes 31 and 32 are formed. Thus, the composite filter excellent in an isolation characteristic is constituted with a simple construction.
