ELECTRONIC DEVICE COMPRISING SURFACE ACOUSTIC WAVE FILTER
Abstract:
An electronic device according to an embodiment includes: an antenna, a filter configured to pass a signal of a specific frequency band among signals transmitted and received through the antenna, and a processor configured to control the filter to pass the signal of the specific frequency band. The filter includes: a first substrate, a second substrate facing the first substrate, a first group of electrodes disposed inside the first substrate, a second group of electrodes disposed inside the second substrate, a first transducer electrode including a first group of lines, a second transducer electrode including a second group of lines disposed to alternate with the first group of lines, and a power supply configured to apply voltages to the first group of electrodes and the second group of electrodes. The processor is configured to cause at least one of the second group of lines to be separated from the first substrate, by controlling the power supply based on a frequency of a signal to be passed through the filter.
