Abstract

The invention discloses a radio frequency circuit, a radio frequency circuit control method and a device and electronic equipment, and belongs to the technical field of electronic equipment. Wherein the radio frequency circuit comprises a first radio frequency transceiver, a second radio frequency transceiver, a first radio frequency module, a second radio frequency module, a third radio frequency module, a double-pole-double-throw switch, a first antenna, a second antenna and a third antenna, and the isolation degree between the third antenna and the second antenna is larger than that between the first antenna and the second antenna; a first port of the first radio frequency transceiver is connected with a first end of the first radio frequency module, and a second end of the first radio frequency module is connected with the first antenna and the third antenna through the double-pole-double-throw switch; a second port of the second radio frequency transceiver is connected with a first end of the second radio frequency module, and a second end of the second radio frequency module is connected with the first antenna and the third antenna through the double-pole-double-throw switch; and a third port of the second radio frequency transceiver is connected with the second antenna through the third radio frequency module. According to the scheme, the problems of high implementation difficulty and poor performance of a radio frequency circuit scheme for WIFI 5G and N79 are solved.

Description

technical field [0001] The application belongs to the technical field of electronic equipment, and in particular 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), 5G frequency bands are gradually increasing. At present, frequency bands such as N41, N77, N78, and N79 are initially divided. Table 1 lists NR (new air interface) N79 and WIFI (mobile hotspot) 5G frequency range, the frequency interval between the two is 150MHz. The frequencies of the two are very close, and it is difficult to provide sufficient out-of-band rejection by adding filters in 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] format frequency ba...
