CONTROLLED ACOUSTOELECTRONIC DEVICE

摘要

FIELD: radio engineering, communication.SUBSTANCE: method is carried out using an acoustoelectronic device which employs an acoustic line which consists of a monocrystal of a lanthanum-strontium manganite composition LaSrMnO(0.12?x?0.18) with thermally controlled speed of volume or surface acoustic waves near structural phase transition. The device has an acoustic line having at its ends wideband volume or surface acoustic wave converters, and a thermoelectric temperature controller.EFFECT: design of a controlled acoustoelectronic device capable of operating on both volume and surface acoustic waves.3 dwg
