Note: The modem, the remote M&C, OMT, and the antenna are not part of the KST-2000A system and are shown for reference only.
  • Page 21 Ku- Band Satellite Transceiver Revision 9 Introduction MN/KST2000AB.IOM The HPA receives the Ku-Band input from the converter and amplifies it to the user-selected level. For KST-2000A/B SSPAs of ≤ 8 Watts, prime power is supplied by the converter via the M&C cable, while SSPAs > 8 Watts require a separate power source. The output power of the SSPA is set by the user via the remote M&C or keypad, and this output is connected to the feed of the antenna via WR-75 waveguide.
