<p>PROBLEM TO BE SOLVED: To provide an electronic circuit capable of obtaining an excellent frequency characteristic.SOLUTION: An electronic circuit 100 of the invention comprises: a switch 12 that comprises ports A-D, and selects a port to be connected with an antenna 10 from the ports A-D; a duplexer 22 connected between the port B among the ports A-D and terminals Tx22 and Rx22; a duplexer 24 connected between the port C among the ports A-D and terminals Tx24 and Rx24, and having a passband different from a first filter; and an inductor L1 one end of which is connected with the port D among the ports A-D and the other end is grounded. The switch 12 selects the ports B, C, and D among the ports A-D if at least one of transmission and reception of a signal included in a communication band of the duplexer 22, and at least one of transmission and reception of a signal included in the passband of the duplexer 24 are performed at the same time.</p> |
