Patent ID: 7697888

Claim:
Outdoor unit of a reception terminal including a return channel, wherein the return channel (BUC) comprises: a local oscillator providing a signal with a frequency that can be selected from at least two frequencies, a transposition means that transposes a signal to be transmitted using the signal provided by the local oscillator, a wideband filtering means that allows through signals whose frequency corresponds to the transposed signal independently from the frequency of the local oscillator, and a configurable rejection filter depending on the frequency selected for the local oscillator; wherein the configurable rejection filter comprises a guided structure with a replaceable cover, wherein said replaceable cover may be either: a cover including cavities or slots, which configures said configurable rejection filter into a band rejection filter that rejects a bandwidth corresponding to a leak of the transposition frequency, or a flat cover, which causes the configurable rejection filter to operate as a substantially non-filtering element.
