Abstract

The present application discloses a radio frequency circuit, a radio frequency circuit control method, device and electronic equipment, belonging to the technical field of electronic equipment. The radio frequency circuit includes first and second radio frequency transceivers, first, second and third radio frequency modules, double-pole double-throw switches, first, second and third antennas, and the connection between the third antenna and the second antenna is The isolation degree is greater than the isolation degree between the first antenna and the second antenna; the first port of the first radio frequency transceiver is connected to the first end of the first radio frequency module, and the second end of the first radio frequency module is connected to the double pole double The throw switch is connected with the first antenna and the third antenna; the second port of the second radio frequency transceiver is connected with the first end of the second radio frequency module, and the second end of the second radio frequency module is connected with the first end of the second radio frequency module through the double pole double throw switch. An antenna is connected to the third antenna; the third port of the second radio frequency transceiver is connected to the second antenna through the third radio frequency module. This solution solves the problems of difficult implementation and poor performance of RF circuit solutions for WIFI 5G and N79.

Description

technical field [0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a radio frequency circuit, a radio frequency circuit control method, device and electronic equipment. Background technique [0002] With the rise of the fifth-generation mobile communication technology (5G), the 5G frequency band has gradually increased. At present, the frequency bands such as N41, N77, N78, and N79 are initially divided. Table 1 lists the NR (new air interface) N79 and WIFI (mobile hotspot) 5G frequency range, the two frequencies are separated by 150MHz. The frequencies of the two are so close that it is difficult to provide adequate out-of-band rejection by adding filters to the transmit or receive path. When the N79 and WiFi 5G work at the same time, due to insufficient antenna isolation and out-of-band suppression of the RF channel, it will cause serious interference in the receiving channel. [0003] standard fr...
