Abstract: The present invention relates to a metalized waveguide interface (1) for providing a galvanically isolated waveguide connection for a propagating signal, between a standardized waveguide (2) and a, to the standardized waveguide non-compatible, metalized chip-level waveguide (3). The metalized waveguide interface (1) is configured such that a first open-ended quarter wavelength waveguide (31) and a second open-ended quarter wavelength waveguide (32) is obtained along the directions d1 and d2, respectively, when the metalized chip-level waveguide (3) is mounted on the support surface (5). The interface is further configured such that third open-ended quarter wavelength waveguide (33) is obtained between the third surface portion (9) and the metalized chip-level waveguide (3) when the metalized chip-level waveguide (3) is mounted on the support surface (5).

Abstract: A microwave radio system and a method of generating an operational frequency in the microwave radio system. The microwave radio system includes at least one radio link. Each radio link has one or more radio unit(s). Each radio link has a common local oscillator (LO) which is configured to transmit a common LO frequency signal to each of the radio units of each radio link. Each radio link has a respective joint transmission line arranged to be coupled to each respective radio unit and configured to carry a plurality of signals comprising the common LO frequency signal to each of the respective radio units of each radio link. The common LO is arranged remotely from the one or more radio unit(s) and each radio unit is configured to receive and convert the transmitted common frequency signal of the common LO to an operational radio frequency of each radio unit.
