Abstract
A band translation method and device for selecting two or more desired frequency bands of data and bandstacking the two or more desired frequency bands of data into a single output.
Claims19
A band-stacked low-noise block converter, comprising:
- a first input configured to receive a first input signal in a first input frequency band;
- a first oscillator configured to output a first oscillator signal at a first frequency;
- a first mixer operationally connected to the first input and to the first oscillator, the first mixer configured to mix the first input signal and the first oscillator signal into a first mixer output;
- a second input configured to receive a second input signal in a second input frequency band;
- a second oscillator configured to output a second oscillator signal at a second frequency;
- a second mixer operationally connected to the second input and to the second oscillator, the second mixer configured to mix the second input signal and the second oscillator signal into a second mixer output;
- a first combiner operationally connected to the first mixer output and to the second mixer output, the first combiner configured to frequency stack the first mixer output and the second mixer output into a first combiner output;
- and
- a band translation block connected to at least the first combiner output, the band translation block configured to process requests and to output specific bands contained in at least the first combiner output.

A method of band-stacking signals received at a low-noise block filter, comprising:
- receiving one or more input signals in a first input frequency band;
- receiving one or more input signals in a second input frequency band;
- mixing each of the input signals in the first input frequency band with a signal having a first local oscillator frequency to form one or more first mixer outputs;
- mixing each of the input signals in the second input frequency band with a signal having a second local oscillator frequency to form one or more second mixer outputs;
- combining at least one first mixer output with at least one second mixer output to form at least one combiner output;
- routing the at least one combiner output to a band translation block;
- and
- providing output from the band translation block in response to a request, the output containing at least one specific band from the at least one combiner output.
5 more elements
A band-stacked low-noise block converter, comprising:
- first and second inputs configured to receive first and second input signals in first and second input frequency bands respectively;
- a first mixer configured to mix the first input signal and a first oscillator signal into a first mixer output;
- a second mixer configured to mix the second input signal and a second oscillator signal into a second mixer output;
- an auxiliary input configured to receive an auxiliary input signal in an auxiliary input frequency band;
- and
- a band translation block having two outputs, the band translation block operationally coupled to the auxiliary input and the first and second mixer outputs, the band translation block configured to process requests and to output specific bands via the two outputs.
