Abstract

PURPOSE: To obtain a simple, small-size and light-weight elastic surface wave oscillator which requires no DC power source for large voltage, by constituting commonly a distribution feedback-type resonator and a means for obtaining a desired electric field by two comb-shaped electrodes.
CONSTITUTION: Comb-shaped electrodes E1 and E2 are so formed on main face 2 of pieze-electric semiconductor substrate 1 that one electrode element e of one electrode E2 may be arranged between adjacent electrode elements e of other electrode E1, and DC power source 7 is connected between electrodes E1 and E2, thereby obtaining distribution feedback-type elastic surface wave oscillator in the region where electrodes E1 and E2 are formed on substrate 1. In this case, since a means for obtaining the constitution of a distribution feedback-type resonator and a means for obtaining electric field d in substrate 1 are constituted by electrodes E1 and E2 common to them, a simple, small-size and light-weight constitution can be obtained. Then, DC power source 7 eliminates the need to have a large voltage.
