Abstract

PURPOSE:To put outputs from several output electrodes in phase by providing delay time adjusting methods on an elastic surface wave propagation path. CONSTITUTION:An elastic surface wave filter which covers the UHF band by dividing it into two has delay time adjusting methods 7 and 8 provided on substrate 3. Delay time adjusting methods consists of a worked substrate or metal strips and put electric signals, extracted from two electrodes, in phase. As for high and low bands obtained by dividing the UHF band, a band connecting the both is corrected to set even-interval frequency standard over the entire range of the UHF band.
