Abstract
A radio frequency circuit includes: a first, second, and third switch, a first and second phaser circuit, and a combiner. When the first switch is configured to connect the first phase shifter circuit with the combiner and the second switch is configured to connect the second phase shifter circuit with the combiner, a transmission path for the high-frequency RF signal is cut off relative to the medium-frequency RF signal and a transmission path for the medium-frequency RF signal is cut off relative to the high-frequency RF signal, so as to perform CA of the high-frequency and medium-frequency RF signal to obtain a first aggregation signal, and the combiner performs CA on the first aggregation signal and a low-frequency signal.
