Abstract: The present invention relates to a process for securing to a metal support at least one microwave electronic module made on a substrate one of whose faces forms an earth plane. The process consists in depositing between the face forming the earth plane and the metal support, at least one strip of conducting adhesive (12',14',19',20') at the level of the zones of breakage of the earth plane. The invention applies to the microwave field.

Abstract: The invention proposes a transmitting/receiving device comprising at least one transition zone (2 and 3) which comprises a means (7) of transforming a polarized wave of a first polarization into an electrical signal; a second means (8) of transforming an electrical signal into a polarized wave of the second polarization; and a first filtering zone (4) placed between the antenna and the transition zone, the first filtering zone comprising a waveguide filter polarized in the second polarization direction, the said filter being transparent in the first polarization direction.

Abstract: The invention relates to VHF adapters for cable networks of the ODU type. It consists in using two conversion chains, up and down, in which a very stable single reference oscillator (403) drives means (404, 405, 410, 423) of generating the VHF and IF local frequencies common to these two conversion chains. A very selective surface wave filter (417) makes it possible to reject the frequency of the local oscillator at the level of the first intermediate frequency. It makes it possible to obtain a DOCSIS compatible millimetre MWS ODU whose frequency stability and spectral purity satisfy the constraints of the cable standard without undertaking spectral inversion of the signals transmitted and received.

Abstract: The invention proposes an H-plane filter with inductive irises which exhibits a quasi-elliptic response while retaining the same compactness as a filter having a Chebyshev response. The invention furthermore makes it possible to use a large number of transmission zeros. For this purpose, there is proposed a waveguide filter comprising at least one cavity (4) delimited by at least two inductive irises (7). The filter furthermore comprises at least one floating insert (1) placed in one of the inductive irises (7). The invention is also a process for manufacturing the waveguide filter incorporating at least one insert.
