C BAND LNB BLOCK DIAGRAM
C-Band Low Noise Block Converters (LNBs) - General
Redundant C-Band LNB systems minimize system downtime due to LNB failure by providing a spare LNB and an automatic means of switching to the spare upon failure of a primary LNB. A 1:1 system provides one spare LNB for one primary LNB. A 1:2 system provides a spare LNB for either of two primary LNBs.

PDF filethe LNB. A combination of Low Noise amplifier + Block converter is referred to as an LNB. A block diagram of a commercial LNB is shown in Figure 2. The Block Converter consists of 4 important sections as shown in Figure 2. MIXER The Block Converter uses the Hetrodyne principle for conversion of a block of S, C or KU Band frequencies to the IF or
Ku-Band Low Noise Block Converters (LNBs) - General
Ku-Band Low Noise Block Converter is specially designed for satellite earth station and other telecommunications applications. Utilizing state-of-the-art HEMT and GaAs FET technology, this block converter has been designed for both fixed and transportable applications.
