Tuning switch module, antenna assembly and electronic equipment

Abstract

The embodiment of the invention provides a tuning switch module, an antenna assembly and electronic equipment. The tuning switch module comprises a first switch, a first matching circuit and a secondmatching circuit; the first switch comprises a first connection end and a plurality of second connection ends opposite to the first connection end; the first connection end is used for being connectedwith an antenna radiator, the plurality of second connection ends are used for transmitting antenna signals of different frequency bands, and one of the second connection ends is connected with a first channel and a second channel; the two ends of the first matching circuit are connected with the first channel and the ground; the first matching circuit is used for matching the antenna signals ofthe first frequency band received by the first channel; the impedance of the second matching circuit is different from the impedance of the first matching circuit, and the two ends of the second matching circuit are connected with the second channel and the ground; and the second matching circuit is used for matching the antenna signals of the first frequency band emitted by the second channel. The transmission and reception of the antenna signals of the same frequency band are tuned separately, and can be both tuned to the optimal efficiency points.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a tuning switch module, an antenna assembly and electronic equipment. Background technique [0002] With the development of network technology and the improvement of the intelligence of electronic equipment, users can realize more and more functions through electronic equipment, such as calling, chatting, playing games and so on. Wherein, the user implements signal transmission through the antenna of the electronic device when playing games or browsing webpages with the electronic device. [0003] At present, because the transmitting antenna signal and the receiving antenna signal are tuned on the same channel, and multiple frequency bands share one tuning channel, and because the antenna signal transmitted in the same frequency band and the received antenna signal have different frequencies, some receiving and transmitting antennas in the same frequency ba...

AI Technical Summary

Problems solved by technology

[0003] At present, because the transmitting antenna signal and the receiving antenna signal are tuned on the same channel, and multiple frequency bands share one tuning channel, and because the antenna signal transmitted in the same frequency band and the received antenna signal have different frequencies, some receiving and transmitting antennas in the same frequency band The signal frequency differs by hundreds of megabytes, so the antenna transmitting antenna signal and receiving antenna signal cannot be tuned to the best efficiency point at the same time. It is often necessary to ensure the transmission performance at the expense of the reception performance, or to ensure the reception performance at the expense of the transmission performance
