Abstract

The embodiment of the invention discloses a radio frequency circuit and electronic equipment, and aims to solve the problems of large difference loss and poor isolation of a radio frequency circuit element designed at present. The invention comprises a transceiver, and a first transmitting path, a first receiving path, a second receiving path, a second transmitting path, a third receiving path anda fourth receiving path. The first transmitting path, the first receiving path, the second receiving path, the second transmitting path, the third receiving path and the fourth receiving path are respectively connected with the transceiver. A three-pole three-throw switch is connected with a first antenna group in the first transmitting path, a first receiving path and a second receiving path. Adouble-pole double-throw switch is used in the second transmitting path and the third receiving path to be connected with the second antenna group, and due to the fact that the element difference lossof the double-pole double-throw switch is small, the element difference loss caused when a plurality of three-pole three-throw switches are used can be effectively reduced when one double-pole double-throw switch is used in the radio frequency circuit. Meanwhile, switching paths of the double-pole double-throw switch are few, and the isolation degree is better, so that the signal interference can be reduced.

Description

technical field [0001] The invention relates to the field of radio frequency front-end technology, in particular to a radio frequency circuit and electronic equipment. Background technique [0002] With the popularization of mobile smart terminals, users' demand for data traffic continues to increase. From 4G applied to multimedia and broadband, the rate is 100M ~ 1Gbps, and the peak rate of 5GNR (New Radio, new air interface) can reach 20Gbps. The increase in rate requires 5G to have 4*4MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) technology. At present, the operating frequency required for 5G mobile electronic devices is getting higher and higher, and the bandwidth is getting bigger and bigger, resulting in large component loss and poor isolation. Contents of the invention [0003] Embodiments of the present invention provide a radio frequency circuit and electronic equipment to solve the problems of large dropout and poor isolation of radio fre...
