This specification defines the Low Noise Block downconverter (LNB) intended for the satellite data communication
downlink application in the Ku-band.
This LNB has a combined 3-stage HEMT amplifier and block downconverter with Phase Locked Local, which is
constituted with a S-band VCO, Multiplier, Loop Filter and TCXO providing high stability and low phase noise.
All specifications shall apply throughout the full range of the specified environmental conditions unless otherwise
specified.
