Abstract

PURPOSE:To improve the matching performance of a synthesizer, by adding a variable capacity element to the point of synthetization when the outputs of a pair of filters are synthesized after giving the compensation of phase to these outputs via a coaxial cable. CONSTITUTION:The outputs of filters 44 and 45 are applied to a branching synthesizing circuit part 40 via phase controlling cables 46 and 47. The length of the cable 46 is selected so that the impedance is opened at the point near the center frequency of the pass band of the filter 45. In the same way, the length of the cable 47 is selected so that the impedance is opened at the point near the center frequency of the pass band of the filter 44. A variable capacity element 49 is provided to ensure the matching in case an output terminal 43 is added.
