4PPX161E Series
Band IV/V (UHF) PeakPower+^TM bandpass filter

Rev : 03 | Rev date : 17 Nov 2020

The RFS 4PPX161E is designed for global filtering applications associated with DTV television transmission. It is a 4-pole filter incorporating one cross coupling to meet global mask requirements. The filter is water cooled.

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 & 8 MHz channels for global applications.
External, non-invasive coupling adjustment.
Tunable for ETSI, ISDB-T and ATSC applications.
-5 to 55 degree ambient temperature operation.
Water cooled.
