Abstract
The present disclosure provides a high-frequency circuit including a matching circuit capable of adjusting the input/output impedance of a high-frequency device to an optimal value, even if the high-frequency device includes a circuit element whose input/output impedance varies upon the variation in the operating frequency, and provides a transmission and reception circuit including the high-frequency circuit. The high-frequency circuit includes a first high-frequency device, a second high-frequency device electrically connected to the first high-frequency device, and a matching circuit connected between the first high-frequency deviceand the second high-frequency device. At least one of the first high-frequency deviceand the second high-frequency device includes a variable device and has a changeable operating frequency. The matching circuit includes at least one variable device capable of performing impedance matching in accordance with operating frequencies of the first high-frequency device and the second high-frequency device.
