摘要： An automatic load-matching circuit for microwaves, disposed on a transmission line between a signal source and a load. Signal detection means for detecting a travelling wave component and a reflected wave component and for producing outputs corresponding to the absolute value of reflection coefficient .GAMMA., the cosine products .vertline..GAMMA..vertline. cos .theta., and the sine product .vertline..GAMMA..vertline. sin .theta. for controlling an automatic matching means, which includes three matching elements, each having an adjustable short-circuit length, disposed on the transmission line with a separation of odd number multiples of 1/8 of a wavelength along the transmission line. The first and third matching elements are connected such that in response to a change in the short-circulating length of one of the first and third matching elements, the short-circuiting length of the other of the first and third matching elements changes in a corresponding opposite manner. The first and third matching elements are both driven by either the cosine product output or the sine product output, and the second matching element is driven with the one of the cosine and sine product outputs which is not driving the first and third matching elements.
