Abstract
A radio frequency circuit includes a power amplifier, which supports Power class 2, a first filter, which is connected to the power amplifier, which supports Power class 3, and which has a passband including the uplink operating band of Band A for FDD, a second filter, which is connected to the power amplifier, which supports Power class 3, and which has a passband including the uplink operating band of Band A, and a third filter, which is connected to the power amplifier, which supports Power class 2, and which has a passband including Band B for TDD. Assuming a transmit signal in Band A, which supports Power class 2, from the power amplifier is to be output, a transmit signal in Band A is split for output to the first filter and the second filter. Assuming a transmit signal in Band B, which supports Power class 2, is to be output, a transmit signal in Band B is output from the power amplifier to the third filter.
