Low-noise block downconverter and method for the same

机译:低噪声块下变频器及其方法

摘要

An LNB downconverter comprising: two LNBs configured to receive their respective satellite signals: the first and second LNB being configured to output, four IF signals of different polarization and frequency range to a respective first and second Cross-bar Switch (CBS); wherein the first and second CBS, are configured to accept four RF inputs, and routing them, to any of four outputs, as configured by a Controller: wherein outputs of CBSs are connected to respective Satellite Channel Routers (SCRs) configured by the Controller to shift the frequency of their input signals to fixed intermediate frequencies; wherein outputs of SCRs are connected to respective Band Pass Filters (BPFs) whereas the fixed intermediate frequencies of SCRs are different and wherein the band passed by each BPF is non-overlapping; an Adder adding the signals on different frequencies, output by each BPF, to form a single output signal comprising data from both satellite signals.
