HIGH FREQUENCY CIRCUIT, HIGH FREQUENCY COMPONENT, AND COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a high frequency circuit compatible with different communication systems, and that has a high receiving sensitivity by which a transmission power loss is suppressed, and to provide a high frequency component, and a communication device using the same.

SOLUTION: A high frequency circuit at least has: first and second antenna terminals; a transmission terminal and first and second reception terminals for a first communication system; and a switch circuit that selects the first and second antenna terminals to be connected with the transmission terminal. A matching circuit is arranged in each of a signal path connecting the switch circuit with the first antenna terminal and a signal path connecting the switch circuit with the second antenna terminal.
