Radio frequency circuit and electronic equipment

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 radio frequency circuit comprises a transceiver, and a first receiving path, a first transmitting path, a second transmitting path, a second receiving path, a third receiving path and a fourth receiving path which are respectively connected with the transceiver. A double-pole double-throw switch is connected with a first antenna group in a first transmitting path, afirst receiving path and a third receiving path, a double-pole double-throw switch is connected with the second antenna group in the second transmitting path, the second receiving path and the fourthreceiving path, and the element difference loss of the double-pole double-throw switch is small, so that the element difference loss caused by using other switches can be effectively reduced by usingthe double-pole double-throw switch in the radio frequency circuit, and the signal receiving and transmitting performance is improved; meanwhile, the switching paths of the double-pole double-throw switch are few, and the isolation degree is better, so that the signal interference can be effectively 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.
