    ... Introduction 1 Introduction The STV6120 dual tuner has four identical wideband RF inputs. The switch matrix 4:2 allows the selection of the appropriate RF input for each down-conversion path. After the matrix, there is a high-frequency low-pass filter followed by two down mixers. Each mixer, which down-converts the signal to baseband, is followed by a low-pass filter and amplifying stages ...
