8PPXX272E Series
Band IV/V (UHF) PeakPower+TM 30kW bandpass filter
The RFS 8PPXX272E is designed for global filtering applications associated with DTV television transmission. It is an 8-pole fan cooled filter incorporating dual cross couplings. 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.
- 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 – 620MHz).
-
Adjustable bandwidth, available for 6 and 8 MHz channels for global applications.
-
External coupling adjustment simplifies tuning.
- All data presented upon field measured results.
- 115V (50/60Hz) and 230V (50/60Hz) fan cooling kits available in place of liquid cooling.
