在固态中波发射机输出网络的调试中,阻抗匹配网络的调试是其中的重点和难点,我中波发射中心目前各主备机已全部实现固态化,在厂家技术人员的调试过程中,本人积极参与、认真学习、探索,从中获取了许多宝贵知识和经验,现就其中的阻抗匹配网络的原理与调试作一系列阐述。全固态发射机功率合成器的输出口阻抗等效到发射机输出的负载阻抗,通常不会正好等于馈线波阻抗。匹配网络的作用就是把馈线阻抗调整为合成器的输出阻抗,T、π网络都能胜任这种职责。相对固 In the debugging of the output network of the solid state wave transmitter, the debugging of the impedance matching network is the key point and the difficulty therein. At present, all the main and standby machines of the medium wave transmitting center have been solidified. During the debugging of the factory technicians, Actively participate in, conscientiously study, explore, from which gained a lot of valuable knowledge and experience, now on the impedance matching network theory and debugging for a series of elaboration. The output impedance of an all-solid-state transmitter power combiner is equivalent to the load impedance of the transmitter output and usually does not exactly equal the feed-wave impedance. Match the role of the network is to adjust the feeder impedance of the output impedance of the synthesizer, T, π network can do this duty. Relatively solid
