Description
technical field [0001] The present invention relates to a kind of equipment for security inspection, detonation and technical investigation, and more specifically relates to a portable 2.4G non-linear node detection system. Background technique [0002] In the existing detection technology for detection devices containing semiconductors, the nonlinear junction detector has become a routine detection tool. The detection principle is to use the harmonic re-radiation characteristics generated by the electronic component transistor (PN junction). When the nonlinear node (PN junction) receives the fundamental radiation, it can generate a strong second harmonic, while the metal generates Is the strong third harmonic, the application of the nonlinear junction detector is to detect the electronic device in the object under test. However, the traditional nonlinear node detector adopts a split structure design, and its probe is separated from the host and connected by radio frequency...
