Abstract

The present invention relates to a circuit for phase and amplitude modulation. The modulation circuit comprises a first distribution circuit receiving the local signal, two mixers, a phase-shifting circuit, a second distribution circuit producing the output signal, these modulators and these distribution circuits incorporating one transformer each. According to the invention, all these transformers are produced by impression or etching on one or other of the faces of a same support. <IMAGE>
