Abstract
The application provides a radio frequency circuit, including a radio frequency module, a first combiner, a second combiner, a main antenna, and a secondary antenna. The main antenna is connected to the radio frequency module through the first combiner, and the secondary antenna is connected to the radio frequency module through the second combiner, wherein the radio frequency module transmits a main antenna signal of at least one frequency band to the secondary antenna through the second combiner, and transmits a secondary antenna signal corresponding to the frequency band to the main antenna through the first combiner.
