<Description>
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 VCO, SPD (Sampling Phase Detector), Loop Filter and
Reference Recovery VCXO providing low phase noise. All specifications shall apply throughout the full range of the
specified environmental conditions unless otherwise specified.
