摘要： An R.F. balanced mixer comprises on an insulating substrate (3) with opposed major surfaces a balanced first transmission line having a pair of conductors (18, 19) on a first major surface and an unbalanced second transmission line having a strip conductor (15) on one major surface and a ground conductor (13) on the side of the substrate (3) remote from the strip conductor (15). Two diodes (24, 25) are conductively connected between the pair of conductors (18, 19) of the first line and the strip conductor (15) of the second line to form an arrangement operable as a 180° hybrid junction, the first line coupling an R.F. signal to the diodes (24, 25) and the second line coupling an L.O. signal to and an I.F. signal from the diodes (24,25). To reduce the impedance of the I.F. signal ground return path and inhibit resonant effects, the pair of conductors (18, 19) of the first line to which the diodes (24, 25) are respectively connected are on the same major surface as the strip conductor (15) of the second line and are coupled to the ground conductor (13) of the second line by means which include conductive connections (e.g. 33, 34) through the substrate (3) and which present a low impedance to the L.O. and I.F. signals.

摘要： In an R.F. circuit with at least one R.F. transmission line (15, 13) comprising a ground plane (13) on an insulating substrate (3) and with two diodes (24, 25) respectively D.C.-connected to two portions (38, 39) of the ground plane (13) mutually D.C.-isolated by a slot (37) therein to enable the diodes (24, 25) to be biased, the substrate (3) is mounted in a housing (1, 2) of conductive material, and the two portions (38, 39) of the ground plane (13) are mutually R.F.-coupled via the conductive material, one of the portions (39) being conductively connected to an adjacent housing member (2) and the other portion (38) being separated therefrom by a thin insulating layer. The slot (37) is such as to inhibit coupling of R.F. energy out of the circuit into the slot (37), suitably being very narrow, e.g. 20 µm, so as to form a further transmission line with a very low characteristic impedance and also to have a high attenuation along its length for operation at mm-wavelengths.
