Abstract:
A radio frequency circuit includes: a first filter having a passband corresponding to a first frequency band of at least 5 gigahertz and less than a predetermined frequency; a second filter having a passband corresponding to a second frequency band of at least the predetermined frequency; a switch configured to switch connection of the first filter between a first transfer circuit and a third transfer circuit. The first filter is connected between a first antenna connector terminal and the first transfer circuit and between the first antenna connector terminal and the third transfer circuit. The second filter is connected between a second antenna connector terminal and a second transfer circuit. A first communication system or a second communication system is a wireless local area network (WLAN) system.
