Document Type and Number:
WIPO Patent Application WO/2024/078260
Kind Code:
A1
Abstract:
A radio-frequency switch and a control method therefor, and an electronic device. The radio-frequency switch comprises a radio-frequency signal input end and a radio-frequency signal output end, wherein the radio-frequency signal input end is connected to a first power source by means of a radio-frequency isolation device; at least one section of a first impedance transformation line is connected between the radio-frequency signal output end and the radio-frequency signal input end, and the first impedance transformation line is configured to realize impedance transformation from a short circuit to an open circuit; two ends of the first impedance transformation line are respectively connected to a grounding end or a second power source by means of a first PIN diode and a second PIN diode in a switchable manner; and the voltage of the second power source is higher than the voltage of the first power source.
