Beschreibung
Zusammenfassung:	An electronic circuit includes: a switch that includes ports, and selects a port to be connected to an antenna from among the ports; a first filter connected between a first port and a first terminal, and having a pass band which overlaps with a transmission band of a first band; a second filter connected between a second port and a second terminal, and having a pass band which overlaps with a transmission band of a second band; a third filter connected between a third port and a third terminal, and having a pass band which overlaps with reception bands of the first and the second bands; wherein when a signal in the first band is transmitted and received, the switch selects the first and the third ports, and when a signal in the second band is transmitted and received, the switch selects the second and the third ports.
