Radio frequency circuit, antenna module, and communication device

A radio frequency circuit, comprising:

• a first filter having a first passband that corresponds to a portion of a frequency range of a first communication band that is a single continuous band;
• a second filter having a second passband that corresponds to a portion of the frequency range of the first communication band, the second passband being different from the first passband;
• a power amplifier configured to amplify an intermediate frequency transmission signal;
• a low-noise amplifier configured to amplify an intermediate frequency reception signal;
• a first mixer configured to perform a frequency conversion on the intermediate frequency transmission signal to obtain a millimeter-wave transmission signal that is a signal in a millimeter-wave frequency range included in the first communication band;
• a second mixer configured to perform a frequency conversion on a millimeter-wave reception signal to obtain the intermediate frequency reception signal, the millimeter-wave reception signal being a signal in the millimeter-wave frequency range included in the first communication band;
• and
• a first switch configured to switch between connecting the first filter and the first mixer and connecting the first filter and the second mixer, and to switch between connecting the second filter and the first mixer and connecting the second filter and the second mixer,
• wherein the first passband includes a portion of a frequency range of a second communication band allocated as a communication band for time division duplex.
