    摘要: 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 signal reference oscillator drives means of generating the VHF and IF local frequencies common to these two conversion chains. A very selective surface wave filter makes it possible to rject the frequency of the local oscillator at the level of the first intermediate frequency. It makes it possible to obtain a DOCSIS compatible millimeter 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.

    摘要: The module comprises an input/output access point at a first end of a waveguide with a square cross section, called a square waveguide, two access points made of waveguides with a rectangular cross section, called rectangular waveguides, placed side by side at a second end of the square waveguide and a septum positioned in the square waveguide at the end of a separation region common to the two rectangular waveguides in order to allow the production of two circular polarizations of opposite handedness each associated with a rectangular waveguide. The module is arranged so as to form a diplexer in which the septum is included and where the access points by rectangular waveguide are extended by filters, each access point being endowed with a filter provided in order to transmit a frequency band which is different. The steps of the septum are dimensioned so as to compensate for reflections.

    摘要: The present invention relates to a band rejection filter. The band rejection filter includes a first signal transmission channel called a direct channel and a second signal transmission channel called a secondary channel. The direct channel and the secondary channel being designed to introduce at a first rejection frequency a phase difference of 180° between the signal circulating via the direct channel and the signal circulating via the secondary channel. Additionally, the secondary channel includes a filtering element for which the cut-off frequency is different from the first rejection frequency in a way to create a second rejection frequency.
