Abstract

PURPOSE:To prevent the generation of distortion noises at the time of FM-modulation of a reception frequency by providing the passing band of a filter for each center frequency and disallowing two receptin frequencies to have primary-gradient delay characteristics. CONSTITUTION:On the left-hand side of enclosure 20, resonance bars 21...24 are included to form four resonators with lower terminals shorted and upper terminals open, and those resonators are cascaded via totalizing windows 25...27 to form four-stage BPF28 of the distribution constant circuit. On the right-hand side of enclosure 20, resonators similar to those on the left-hand side are provided. Here, a received wave of frequency f1 arriving at common terminal 41 passes through coupled conductor 43 and four resonators of f1 in center frequency and are outputted from common terminal 42 by way of combined conductor 44. On the other hand, a signal of frequency f2 passes through for resonators of center frequency f2 and is sent out from terminal 42 in the same way. Consequently, received wave of frequencies f1 and f2 have not any primary-gradient delay characteristics, and distortion noises at the time of FM-modulation of received wave can be prevented.
