Abstract
A radio frequency circuit is capable of sending a transmit signal of a first communication band and a transmit signal of a second communication band simultaneously and includes a transmit input terminal, a power amplifier capable of amplifying a transmit signal of the first communication band, and a filter connected between the transmit input terminal and an input terminal of the power amplifier. In the filter, a pass band is a band including a transmit band of the first communication band, and an attenuation band is a band including a transmit band of the second communication band.
