Method and device for band translation

摘要

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.

主权项

1. 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.
