SWITCHING CIRCUIT FOR SWITCHING SIGNAL PATH IN WIRELESS COMMUNICATION SYSTEM, AND ELECTRONIC DEVICE COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2022/031070

Kind Code:

A1

Abstract:

The present invention relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate than previous 4th generation (4G) communication systems such as Long Term Evolution (LTE). According to various embodiments of the present invention, a switching circuit in a wireless communication system comprises: a first coil; a second coil electrically coupled to the first coil; a first switch electrically connected to the second coil; a third coil electrically coupled to the first coil; a second switch electrically connected to the third coil; and a control unit configured to control the opening or closing of the first switch and the second switch. The control unit can be configured to close the first switch and open the second switch to form a first path using the first coil and the second coil, and open the first switch and close the second switch to form a second path using the first coil and the third coil.
