LNB

Low Noise Block Downconverter - A device that processes weak satellite signals directed by an antenna reflector into a feedhorn, whilst introducing as little electrical noise as possible in the process. An LNB consists of a microwave detector followed by a high gain, low noise microwave amplifier and a frequency converter, which downconverts a block of frequencies (group of satellite signals) to a lower intermediate frequency range (typically 950 to 2150 MHz). The feedhorn is often integrated with LNB in a single mechanical unit.
