摘要
在现代电子装备功放电路中,对发射脉冲的检测非常重要,如果脉冲过宽或者占空比过高,将导致功放输出功率过高,有超出功放所能承受的负载,并损坏功放的危险,所以在设备工作中检波器检波出视频脉冲,为后续的脉冲测量提供样本。本文设计出一种实用的微波检波器,在实际工作中运行可靠,工作稳定,同时也可以其它工程实践提供参考。
In the modern electronic device, it is very important to transmitter pulse is out of accord with the required parameter, it would device. At the same time, in the transmitter circuit, if the pulse is very the power would be too high and thus damage the transmitter circuit. So a mi the video pulse and provide the sample for the later pulse measurement. A p measure lead to broad or crowave transmitte ormal work duty facto detector is d ractical method is de r pulse. If the of the receive r is over high, igned to detect gned to measure the pulse parameter. Experiment indicates that the circuit could work reliably.
