Title:
ELECTRONIC DEVICE COMPRISING SURFACE ACOUSTIC WAVE FILTER
Document Type and Number:
WIPO Patent Application WO/2021/054768
Kind Code:
A1
Abstract:
An electronic device according to one embodiment comprises: an antenna; a filter for passing a signal of a specific frequency band among signals transmitted and received through the antenna; and a processor for controlling the filter to pass the signal of the specific frequency band, wherein the filter comprises a first substrate, a second substrate facing the first substrate, a first group electrode disposed on the first substrate, a second group electrode disposed on the second substrate, a first transducer electrode including a plurality of first group lines, a second transducer electrode including second group lines alternately arranged with the first group lines, and a power supply unit for applying a voltage to the first group electrode and the second group electrode, and wherein the processor controls the power supply unit on the basis of a frequency of a signal to be passed through the filter so that at least one of the second group lines can be separated from the first substrate.
