Dual-channel passive device power tolerance testing system

Abstract

The invention relates to a dual-channel passive device power tolerance testing system. The dual-channel passive device power tolerance testing system comprises two signal generators. Both the signal generators are correspondingly connected to signal switches. The signal switches are connected to electric bridges through power amplifiers. Each signal switch is connected with two power amplifiers, and connection is switched through switches. The 3dB electric bridges are connected with diplexers through dual-directional couplers. Loads are hung outside the electric bridges. The forward coupling end and the reverse coupling end of each dual-directional coupler are connected with two terminals of a corresponding dual-channel power meter respectively. The diplexers are connected with spectrometers through detection ports, the diplexers are connected to detection parts, and the detection parts are connected with attenuators through filters. Loads are hung outside the detection parts. The attenuators are connected with the spectrometers. The dual-channel passive device power tolerance testing system judges whether the performance of devices is qualified or not by checking the working states and the technical indexes of the devices in peak power and average power, so that the requirements for communication capacity and communication quality of the whole communication system are guaranteed, and system interference is reduced from the source.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a dual-channel passive device power tolerance test system. Background technique [0002] With the increase of the capacity of the power company's communication network, passive devices are becoming more and more important as a very important part of the network. The performance index of passive devices directly affects the network quality of the entire communication system. The performance index of the source device becomes very necessary. [0003] In a multi-channel wireless communication system, the transmission of radio frequency energy will cause resistance and dielectric consumption to generate heat, which will lead to aging, deformation and possible voltage flashover of the device. Among them: the arcing phenomenon is due to insufficient power tolerance, especially the insufficient ability to withstand the peak power, resulting in abnormal heating and ignition, whic...

[0004] In a multi-channel wireless communication system, the transmission of radio frequency energy will cause resistance and dielectric consumption to generate heat, which will lead to aging, deformation and possible voltage flashover of the device

Among them: the arcing phenomenon is due to insufficient power tolerance, especially the insufficient ability to withstand the peak power, resulting in abnormal heating and ignition, which causes the background noise to increase, causing interference to the entire system, and its harm is very serious
