Notes

  • The system analysis has been carried out with reference to an out-of-band noise of -36 dBc
  • Adjacent Channels combination can be implemented independently of the required Mask (e.g.: Critical or Non-Critical): there is no strictly need of 8-Pole Filters to combine adjacent channels

Notes

  • The system analysis has been carried out with reference to an out-of-band noise of -35 dBc
  • Values refer to Power levels ≤ 1 kW.
  • For Power levels > 1 kW, Filter Requirements must be increased according to the increased dB ratio (E.g. 2 kW: increase Filter Requirements by 3 dB)
  • Adjacent Block combination can be implemented independently of the required Mask (e.g.: Critical or Non-Critical): there is no strictly need of 8-Pole Filters to combine adjacent blocks
