Remotely fed module
First Claim
1. A communication system comprising:
- a base station;
a satellite located remote from said base station;
a single signal line connected between said base station and said satellite allowing a first signal, to be transmitted in a first direction from the satellite to the base station, and a second signal, having a different frequency from said first signal, to be transmitted in a second direction from said base station to said satellite;
said satellite comprising a first filter bank that spectrally separates a plurality of first signals at transmitted via said single signal line in said first direction from said satellite and a plurality of second signals transmitted via said single signal line in said second direction to said satellite;
said base station comprising a second filter bank that spectrally separates the plurality of second signals transmitted via said single signal line in said second direction from said base station and the plurality of first signals transmitted via said single signal line in said first direction to said base station; and
said single signal line being connected between said first filter bank and said second filter bank to cause the plurality of first and second signals transmitted via said single signal line between said base station and said satellite to be respectively spectrally separated in said first and second filter banks; and
said first filter bank at said satellite comprising a high-pass/low-pass diplexer comprising a low-pass path and a high-pass path, said second signal being supplied by said diplexer to said low-pass path or said high-pass path;
wherein said satellite comprising a plurality of modules respectively connected to said diplexer that mix said second signal with a third signal supplied to said satellite, to produce the first signal of said satellite.

Abstract
In a method and device for the transmission of a multiplicity of signals having different frequencies between a base station and a module situated at a location remote from the base station via a single, common cable connection, some of the signals being transmitted from the electronic assembly to the module and, in general simultaneously, the remaining signals are transmitted in the opposite direction. Each of the base station and the module has bandpass filter bank therein having a multiplicity of bandpass filters, the number thereof being a function of the number of channels to be transmitted, with which the respectively received signals are spectrally separated from one another so that they are available for further signal processing in the base station, or for further use in the module.

16. A method for communicating between a base station and a satellite located remote from said base station comprising the steps of:
-
connecting said base station and said satellite with a single signal line allowing a first signal, to be transmitted in a first direction from the satellite to the base station, and a second signal, having a different frequency from said first signal, to be transmitted in a second direction from said base station to said satellite; providing said satellite with a first filter bank that spectrally separates a plurality of first signals transmitted via said single signal line in said first direction from said satellite and a plurality of second signals transmitted via said single signal line in said second direction to said satellite; providing said base station with a second filter bank that spectrally separates the plurality of second signals transmitted via said single signal line in said second direction from said base station and the plurality of first signals transmitted via said single signal line in said first direction to said base station; via said single signal line, transmitting between said first filter bank and said second filter bank and spectrally separating the plurality of first and second signals transmitted via said single signal line between said base station and said satellite respectively in said first and second filter banks; and forming said first filter bank at said satellite as a high-pass/low-pass diplexer comprising a low-pass path and a high-pass path, and supplying said second signal by said diplexer to said low-pass path or said high-pass path; wherein at said satellite, connecting a plurality of modules respectively to said diplexer and mixing said second signal with a third signal supplied to said satellite in said modules to produce the first signal of said satellite. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
