CA8PPXX201C-M
Band III (VHF) PeakPower+TM bandpass filter

The RFS CA8PPXX201C-M is designed for global filtering applications associated with DTV television transmission. It is an 8-pole water cooled balanced 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 (174 – 230 MHz).
  • Adjustable bandwidth, available for 6, 7 & 8MHz channels for global applications.
  • External, non-invasive coupling adjustment.
  • Tunable for ETSI, ISDB-T critical and ATSC1.0/ATSC3.0 applications.
  • -5 to 55 degree ambient temperature operation.
  • Water cooled.
