Abstract:
A circuit, electrical device or other apparatus for band stacking and/or band translating multiple transmissions. Such transmissions may be satellite transmissions, terrestrial transmissions, signals carried across a wired network such as a cable network, and so forth. Two sets of left-hand polarized and right-hand polarized signals may be accepted by an embodiment. One left-hand polarized signal and one right-hand polarized signal may be band stacked such that the left-hand polarized signal occupies a first frequency and the right-hand polarized signal occupies a second frequency, thereby permitting the two signals to be transmitted simultaneously across a single transmission line as a first unique signal. The second left-hand polarized signal and second right-hand polarized signal may likewise be combined into a second unique signal for transmission. The first and second unique signals may be stacked as a first stacked output and a second stacked output by a band translating circuit.
