Microwaves - modulator for two phases then during initialization: o, pi with very low losses.

摘要

The invention relates to a modulator according to two phase states 0, p 1 at a very low losses, comprising between an input e, which receives a pure carrier at frequency fo and the output which delivers a carrier wave modulated in two phase states: - a first switching element 17, -, and in parallel to that - a second switching element 18 in series with a line princpale 19 of the length l = lambdao / 2, lambdao being the wavelength corresponding to the frequency fo, - a control system 20 for driving the first element 17 and 18 and block the other. / p & & p & a particular application of the field of microwave transmission.
