Low Noise Converter converters the incoming signal from the satellite (3.6 to 4.2 GHz in the c-band and 10.700 to 12.750 in ku-band) into a lower frequency (900 to 2150 MHz).
Low Noise Converter. An LNA and a conventional box. This device converts one channel at a time. Channel selection is controlled by the satellite receiver. The typical IF for LNCs is 70 MHz.
Lean NOx Catalyst. Catalyst designed to reduce nitrogen oxides from diesel or spark-ignited engine exhaust gases under net oxidizing conditions, i.e., in the presence of excessive amount of oxygen.
