8PPXX270E SERIES
Band IV/V (UHF) PeakPower+^TM 15kW bandpass filter

Rev : 03 | Rev date : 16 Jul 2021

The RFS 8PPXX270E is designed for global filtering applications associated with DTV television transmission. It is an 8-pole natural air-cooled filter incorporating two cross couplings to meet all mask requirements. The 8-pole filter allows for FCC tightening of emission mask in ATSC3.0

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 UHF band (470 – 704 MHz)
Adjustable bandwidth, available for 6 and 8 MHz channels for global applications. External coupling adjustment simplifies tuning.
-5 to 55 degree C ambient temperature operation.
All data presented based on measured results.
