US 5,959,592 A · "IF" bandstacked low noise block converter combined with diplexer

Abstract

An arrangement is provided for combining the video and audio signals from a satellite antenna with other auxiliary input signals producing a frequency stacked band arrangement for transmission by a single cable to a satellite receiver or TV monitor located within a home or structure. Multiple TV input signals from the satellite antenna are processed and separated into intermediate frequency bands which are then combined in a diplexer with one or more auxiliary input frequency bands. The output of the diplexer is connected directly to the signal output terminal at the antenna. All components for performing this combining process are included within the sealed housing of the LNB provided at the satellite antenna. Improved band isolation and reduced noise and interference are produced by the novel arrangement.

Dependent claims

A satellite antenna system for receiving microwave signals and combining these signals with other auxiliary antenna signal sources for transmission of the combined signals through a single conductor cable to a processing unit positioned within a structure, the antenna system comprising;

a) a housing mounted with respect to a satellite antenna, said housing having a wave guide for receiving microwave radio frequency signals from said antenna, a plurality of exterior connectors for connecting a single output conductor cable and incoming auxiliary signal sources, and a cover for sealing said housing to form a weather proof enclosure;
b) one or more low noise block down converter circuits mounted within said housing for receiving, processing and conditioning the microwave antenna radio frequency signals received through said wave guide of said housing;
c) a diplexer circuit positioned within said housing and having a plurality of inputs and a single output connected to the output connector on said housing, the signals from said low noise block down converter circuits being connected to an input of said diplexer circuit;
and
d) one or more auxiliary signal sources connected to said housing connectors and said diplexer circuit input for combining within said diplexer all of the satellite signals and auxiliary signal sources so that the combined signals will be transferred to said processing unit.
