8PPXX202E Series
Band IV/V (UHF) PeakPower+TM bandpass filter

The RFS 8PPXX202E is designed for global filtering applications associated with DTV television transmission. It is an 8-pole fan cooled filter incorporating two cross couplings to meet all mask requirements. The 8-pole filter allows for FCC tightening of emission mask for ATSC 3.0 in the future.

FEATURES / BENEFITS

  • Meet FCC mask requirements plus extra protection for adjacent channels.
  • Very compact for easy integration into equipment.
  • Lowest insertion loss and highest power rating for its size/class.
  • Tunable over UHF band (470 – 710 MHz).
  • Adjustable bandwidth, available for 6, 7 & 8 MHz channels for global applications.
  • External, non-invasive coupling adjustment.
  • Tunable for ETSI and ISDB-T critical and non-critical, and ATSC 1.0/3.0 applications.
  • 115V (50/60Hz) and 230V (50/60Hz) fan cooling kits available in place of liquid cooling.
