Abstract
Microwave circuits, namely the circuits relating to the transmission-reception part and to the filtering of the microwave transceiver, are mounted on one and the same multilayer printed circuit and their electromagnetic insulation comprises, firstly, elements of the printed circuit such as conductive tracks on one of the faces of the printed circuit, metallized holes drilled in the tracks and close to one another so as to fulfil the role of an electromagnetic barrier and, at least in the case of some of them, a conductive plate and, secondly, attached elements with, especially, a thick metal lattice surmounted by a lid, the lattice resting on the conductive tracks.
