Problems solved by technology
[0004] When the GSM850 transmits at high power, the diversity antenna will receive the transmission signal of the main antenna through spatial coupling, and the transmission signal enters the diversity receiving module. When the transmission signal coupled to the diversity receiving module has a large strength (>0dBm), The switch inside the diversity receiving module will generate higher harmonic signals, which will cause the RSE (radiated spurious) test to fail
[0005] For the above-mentioned radiation spurious problem caused by the high harmonic signal generated by the transmission signal entering the diversity receiving module, no effective solution has been proposed so far

The present invention provides a diversity receiving module, a radiation spurious processing method and electronic equipment, and relates to the field of communication technology. Load path), the internal circuit of the diversity receiving module includes a specified number of receiving paths, the load path with the specified impedance is the same load path as the internal circuit of the diversity receiving module, and the internal circuit of the diversity receiving module is used to connect with the antenna path, In order to connect the corresponding receiving channels based on the specified number of channels; the load channel of the specified impedance is used to absorb the harmonic components generated by the coupling of the transmitted signal and the internal switch of the diversity receiving module by connecting with the antenna channel when transmitting the signal. The present invention can effectively reduce the problem of stray radiation.
Description
technical field [0001] The present invention relates to the technical field of communications, and in particular, to a diversity receiving module, a method for processing radiation spurious, and an electronic device. Background technique [0002] With the upcoming 5G mobile communication of mobile phones, more and more devices are used in the radio frequency solution. Due to the limitation of the ornament space, the integration of radio frequency devices is required to be higher and higher. For example, a DIFEM device in the diversity channel has been used at present. Since the DIFEM device is a nonlinear device, it may cause a radiated spurious emission (RSE) problem during use. [0003] RSE is an important test item for mobile phone EMC. The purpose of RSE test is to evaluate the performance of radiated disturbance emission. For a normal mobile phone, in addition to useful signals, stray disturbance signals will also cause disturbance to other useful frequency band signals...
