Title:
WIRELESS CIRCUIT, AND METHOD FOR CONTROLLING WIRELESS CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2014/045729
Kind Code:
A1
Abstract:
In a wireless circuit (1), when a control unit (50) switches the frequency band being used by an antenna (10), the control unit (50) sets the setting value of an impedance variable matching unit (20) after the switch in accordance with a first setting value adjusted by means of the impedance variable matching unit (20) before the switch. As a consequence, communication is prevented from becoming disconnected when the frequency band being used is switched in a wireless circuit provided with a variable matching unit.
