Title:
TRANSMISSION CIRCUIT AND COMPOSITE TRANSMISSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/162639
Kind Code:
A1
Abstract:
This transmission circuit comprises: a plurality of impedance circuits each having a different impedance; a plurality of switch elements, one of which is connected to each of the plurality of impedance circuits; a compensation circuit connected to each of the plurality of switch elements and selectively adding a capacitance value and a resistance value to the transmission circuit; and a control circuit configured to control opening and closing of the plurality of switch elements. The control circuit is configured to selectively change the opening and closing of the plurality of switch elements so as to control the reflection coefficient of the output terminal on the antenna side to rotate in the complex plane.
