Abstract

PURPOSE:To use elastic surface waves to extend the frequency region, by grounding one of a pair of electrodes and by dividing the other into two and by applying a aignal S of a prescribed frequency to one divided electrode and by applying the signal S, a signal So of amplitude zero, and a signal inversion S to the other. CONSTITUTION:Reed screen type electrodes 2 and 4 for input and output are provided apart from each other on a piezolelectric substrate 1 which has a thickness enough to excite elastic surface waves. One electrode 3b of the electrode 2 for input is grounded, and the other electrode is divided into electrodes 3a-1 and 3a-2. The signal S having a carrier of a frequency fC is applied as a reference, signal to the electrode 3a-1, and the signal S, the signal inversion S which has the phase shifted at 180 deg. for the signal S, and a signal S0 of amplitude zero are applied to the electrode 3a-2. The output obtained between terminals A' and 0' of the electrode 4 for output is detected as the difference of amplitude levels.
