Abstract
Disclosed are a filter apparatus for use in a radio apparatus for multiplex radio communication used when a signal is branched, a jig for arranging dielectrics of the filter apparatus for use in a radio apparatus and a method for arranging dielectrics of the filter apparatus for use in a radio apparatus using the jig. A filter apparatus for use in a radio apparatus has a pair of dielectric filters having different frequency characteristics, which are connected to a common circulator, thereby reducing the number of the circulators to realize a reduction of size and a low cost of the radio apparatus and improvement of accuracy in communication.
