Abstract
A symmetrical strip line type microwave circuit, the input-output connection zones of which are made in the following way: PA1 a groove is made in that of the insulating substrates which does not bear the central conductor of the symmetrical strip line circuit, along the contour of the desired connection zone; PA1 the two substrates are bonded together; PA1 the exterior of the structure is protected by electrolytic deposition of a tin-lead alloy; PA1 a counter-groove is made in the first substrate along the contour of the connection zone, and that portion of the substrate located inside the zone is eliminated.
