    Abstract: A transition from microstrip to waveguide comprises a rectangular waveguide and a microstrip structure formed by a resilient substrate (24) having a stripline (26) on one surface and a ground plane (44) on an opposite surface, the conductors (26, 44) being interconnected by viaholes. The substrate (24) is disposed between the side walls (36) and the floor (22) of the waveguide with the ground plane contacting the floor. The stripline extends from one end of the waveguide along a portion of its length. A tapered ridge (38) depends from the ceiling (34) of the waveguide and extends from the other end of the waveguide. A terminal end (40) of the ridge contacts a terminal portion of the stripline under mechanical pressure. The ridge (38) may have a choice of profiles such as triangular, half cosine and half cosine with a semicircular cut-out in the upright edge.

    Abstract: A microwave circuit comprises a printed circuit board (PCB) on which is fabricated a circuit including passive components such as filters (40) formed by printed conductive patterns. In order to enhance the performance of the circuit, selected components such as filters are made with a greater precision on substrate material (41), such as alumina, having a higher dielectric constant than that of the printed circuit board material. The finished component is mounted on the printed circuit board and the conductive pattern is connected by wire bonds (48, 50) to microstrip tracks (51) of the printed circuit board.
