8PPXX161E Series
Band IV/V (UHF) PeakPower+TM bandpass filter

The RFS 8PPXX161E is designed for global filtering applications associated with DTV television transmission. It is an 8-pole 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 UHF band (470 – 862 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 applications.
  • -5 to 55 degree ambient temperature operation.
  • Rodless design - integrated tuning mechanism.
