Electronic device capable of eliminating interference

Abstract

The invention provides an electronic device capable of eliminating interference. The electronic device capable of eliminating interference comprises a first radio component, a second radio component, a quadrature coupler, a first two-way phase shifter and a second two-way phase shifter, wherein the first radio component and the second radio component work at the same frequency band and are used for emitting a first signal and a second signal respectively. The quadrature coupler is used for providing isolation between emission ports of the first radio component and the second radio component and avoiding internal interference when the first signal and the second signal are emitted at the same time. The quadrature coupler is further used for making the field pattern of the first signal and the field pattern of the second signal mutually orthogonal, wherein the first signal field pattern and the second signal field pattern which are mutually orthogonal and are obtained through radiation can restrain external disturbance signals. The first two-way phase shifter and the second two-way phase shifter are used for conducting phase adjustment on the first signal field pattern and the second signal field pattern which are obtained through radiation so as to control the radiation directions of the first signal field pattern and the second signal field pattern. According to the electronic device capable of eliminating interference, mutual interference which may be caused when radio components with the approximately same working band inside an electronic device work at the same time can be avoided, and the external disturbance signals are prevented from being received.

Description

technical field [0001] The invention relates to a radio frequency structure, in particular to an electronic device capable of eliminating interference. Background technique [0002] Extraneous energy that interferes with reception of a desired signal is generally referred to as interference. If there are two radio components with equal or approximately equal emission frequencies in the electronic device, when these radio components operate at the same time, the electronic device may receive internal interference signals and external interference signals at the same time, thereby preventing the intended reception of the desired signal . [0003] For example, for an electronic device equipped with both a Bluetooth communication port and a WiFi communication port, if the working frequency bands of the Bluetooth communication port and the WiFi communication port are the same or approximately the same, the radios emitted by the two may interfere with each other, causing the The...
