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 invention provides a diversity receiving module, a radiation stray processing method and electronic equipment, and relates to the technical field of communications. The diversity reception modulecomprises an internal switch (comprising an internal circuit of the diversity reception module and a load path with specified impedance) of the diversity reception module, wherein the internal circuitof the diversity reception module comprises a specified number of reception paths, the load path with specified impedance is the same as the diversity reception module internal circuit in connectionmode, and the internal circuit of the diversity reception module is used for being connected with an antenna path so as to connect the corresponding reception path based on the specified number of paths; and the load path with the specified impedance is used for absorbing a harmonic component generated by coupling the transmitting signal and an internal switch of the diversity receiving module bybeing connected with the antenna path when the signal is transmitted. According to the invention, the problem of radiation stray can be effectively reduced.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a diversity receiving module, a radiation spurious processing method and electronic equipment. Background technique [0002] With the upcoming 5G mobile communication of mobile phones, more and more devices are used in radio frequency solutions. Due to the limitation of decoration space, the integration of radio frequency devices is required to be higher and higher. For example: currently, the DIFEM device has been used in the diversity channel. Since the DIFEM device is a nonlinear device, it may cause a problem of radiated spurious emission (RSE) during use. [0003] RSE is an important test item for EMC of mobile phones. The purpose of RSE test is to evaluate the performance of radiation disturbance emission. For normal mobile phones, in addition to useful signals, spurious disturbance signals will also cause disturbance to signals in other useful frequency bands. The ...
