US 9,179,170 B2 · Low noise block converter feedhorn

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.

Dependent claims

A low noise block converter feedhorn, comprising:

a signal receiver operative to receive at least a first input signal and a second input signal, the first and second input signals including at least portions of programs, respectively;
a first mixer operative to receive the first input signal from the signal receiver, further operative to mix the first input signal with a first reference signal to create a first translated signal, the first reference signal derived from a first local source;
a second mixer operative to receive the second input signal from the signal receiver, further operative to mix the second input signal with the first reference signal to create a second translated signal;
a third mixer operative to mix the first translated signal with a second reference signal to create a third translated signal, the second reference signal derived from a second local source, the second local source different from the first local source;
and
a first combiner operative to stack the third translated signal and second translated signal into a first single stacked signal, wherein said at least portions of programs in the first single stacked signal are arranged for delivery through a band translating circuit to a television converter device.

3 more elements

A method for converting at least a first incoming transmission and a second incoming transmission to an outgoing transmission, comprising:

receiving a first incoming transmission having a portion of a first program;
receiving a second incoming transmission having a portion of a second program;
multiplexing the first incoming transmission with a first reference signal to create a first multiplexed signal, the first reference signal derived from a first local source;
multiplexing the second incoming transmission with a second reference signal to create a second multiplexed signal, the second reference signal derived from the first local source;
multiplexing the second multiplexed signal with a third reference signal to create a third multiplexed signal, the third reference signal derived from a second local source, the second local source different from the first local source;
and
diplexing the second and third multiplexed signals to create a first band-stacked signal, wherein the portions of the first and second programs in the first band-stacked signal are arranged for delivery through a band translating circuit to a television converter device.
