The invention relates to a radio frequency integrated circuit near-field electromagnetic compatibility testing device and a testing method thereof. The cover is opened and closed. On the side of the electromagnetic shielding shell, there are power line holes and signal line holes respectively. There is a probe cable hole in the center of the top cover of the electromagnetic shielding shell; the near-field probe is vertically fixed on the inner surface of the top cover. Below the cable hole, it is used to receive or transmit electromagnetic interference signals. Test the near-field emission electromagnetic interference of the integrated circuit to obtain the interference range and intensity of the externally radiated electromagnetic interference of the tested radio frequency integrated circuit; test the near-field electromagnetic susceptibility of the radio frequency integrated circuit to obtain the interference range and sensitivity threshold of the tested radio frequency integrated circuit. The invention can be used for near-field emission electromagnetic interference and near-field electromagnetic susceptibility testing of radio frequency integrated circuits.
Description
technical field [0001] The present invention relates to the field of electromagnetic compatibility testing equipment, in particular, to a radio frequency integrated circuit near-field electromagnetic compatibility testing equipment and a testing method thereof, which are used for near-field emission electromagnetic interference and near-field electromagnetic compatibility testing of radio frequency integrated circuits Near-field electromagnetic susceptibility testing. Background technique [0002] Due to the high operating frequency of radio frequency integrated circuits, electromagnetic interference will be generated externally during operation, and it will also be affected by other electromagnetic interference in the same environment. The electromagnetic compatibility of radio frequency integrated circuits is used to evaluate the ability of radio frequency integrated circuits to operate in compliance with the requirements in its electromagnetic environment, and the electro...
