RF circuits and electronic equipment

Abstract

The embodiment of the invention discloses a radio frequency circuit and electronic equipment to solve the problems of large differential loss and poor isolation of radio frequency circuit components currently designed. The radio frequency circuit includes: 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 respectively connected to the transceiver. Connect the first antenna group by using a double pole double throw switch in the first transmit path, the first receive path and the third receive path, and use the double pole double throw switch in the second transmit path, the second receive path and the fourth receive path The switch is connected to the second antenna group. Since the component loss of the double-pole double-throw switch is small, the use of the double-pole double-throw switch in the radio frequency circuit can effectively reduce the component loss caused by using other switches, thereby improving the performance of signal transmission and reception; At the same time, since the double-pole double-throw switch has fewer switching paths and better isolation, 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.
