8PPXX201C
Band III (VHF) PeakPower+TM bandpass filter

The RFS 8PPXX200C is designed for global filtering applications associated with DTV television transmission. It is an 8-pole liquid cooled filter incorporating two cross couplings to meet all mask requirements.

FEATURES / BENEFITS

  • Very compact for easy integration into equipment.
  • Very low insertion loss (lowest for this size).
  • Highest power rating for size/class.
  • Tunable over full VHF band (170 – 230 MHz).
  • Adjustable bandwidth, available for 6 and 7 MHz channels for global applications.
  • External, non-invasive coupling adjustment.
  • Tunable for ETSI, ISDB-T critical and ATSC 1.0 and ATSC 3.0 applications.
  • -5 to 55°C degree ambient temperature operation.
  • Liquid cooled.
