Abstract:
A radio frequency circuit includes: an antenna connection terminal; a UHB transfer circuit that transfers a signal of a first frequency band including at least a part of a frequency band higher than or equal to 3.3 GHz and under 5 GHz; a NR-U transfer circuit that transfers a signal of a second frequency band including at least a part of a frequency band higher than or equal to 6.6 GHz; and a filter having a frequency band including the first frequency band and the second frequency band as a passband. The filter is disposed between the antenna connection terminal and a connection node of the UHB transfer circuit and the NR-U transfer circuit.
