Abstract

The present application relates to a radio frequency system and a communication device. The radio frequency system may include: a transceiver circuit (10); a receiving circuit (20); a first coupling circuit (30), configured to support coupling of a transmit signal on a transceiver path and coupling of a reflected signal of the transmit signal, and output a first forward coupled signal and a first backward coupled signal; a second coupling circuit (40), configured to selectively turn on the receiving path and the coupling path, support coupling of the first forward coupled signal and coupling of the reflected signal, and output a second forward coupled signal and a second backward coupled signal; and, a processing circuit (50), configured to determine second impedance information of the receiving path according to the second forward coupled signal and the second backward coupled signal.
