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.
