6PPXX272E Series
Band IV/V (UHF) PeakPower+TM 30kW bandpass filter

The RFS model 6PPXX272E is designed for mask filtering associated with DTV television transmission. It is a 6-pole fan cooled filter incorporationg dual cross couplings to meet the mask requirements. Natural air cooled and liquid cooled options are also available.

FEATURES / BENEFITS

  • Both fan cooled and liquid cooled filters have equal power handling capability.
  • Very compact for easy integration into equipment.
  • Lowest insertion loss and highest power rating for its size/class.
  • Tunable over UHF band (470 – 620 MHz).
  • Adjustable bandwidth, available for 6 and 8 MHz channels for global applications.
  • External coupling adjustments simplifies tuning.
  • All data presented upon measured results.
  • 115V (50/60Hz) and 230V (50/60Hz) fan cooling kits available in place of liquid cooling.
