Large scale bi-directional user terminal with configurable transmission frequencies

Abstract

The invention proposes an upgradeable product enabling a single circuit to be produced and very easily configured in the factory for a lower production cost. The minimisation of the industrialisation costs is achieved by an increase of production volumes. An outdoor unit of a reception terminal including a return channel, comprises a band-pass filtering means that allows the transposed signals found in a transmission bandwidth to pass, and a rejector filtering means that rejects at least one frequency found in the transmission bandwidth, the rejector filtering means being neutralised when neither the frequency defined in the oscillator nor a multiple frequency of the defined frequency is found in the transmission bandwidth.
