Abstract (en)
[origin: EP0605046A1] Microwave device including at least one transition between a transmission line (24) integrated on a substrate (23) made of a hard material, arranged in a said first microwave cavity (31), and a waveguide (100) formed by a said second microwave cavity (102a, 102b). This transition comprising an open end (25a, 25b) of the integrated line forming a probe introduced over a length l into the cavity of the guide, at a distance D from a short-circuit (42a, 42b) closing the end of the guide. This transition also has an impedance-matching system with, on the one hand, a restriction (33a, 33b) in the dimension of the said first microwave cavity (31) perpendicular to the direction of propagation, over a defined length L parallel to the direction of propagation in the integrated line (24), and, on the other hand, with a restriction in the dimensions of the cross-section of the waveguide in the region (22a, 32a; 22b, 32b) between the probe (25a, 25b) and the plane of the short-circuit (32a, 42b). Application: transitions between microwave ICs and waveguides. <IMAGE>
