CA6PPXX271E-M
Band IV/V (UHF) PeakPower+^TM bandpass filter

Rev : 02 | Rev date : 03 Jun 2021

The RFS CA6PPXX271E-M is designed for global filtering applications associated with DTV television transmission. It is a 6-pole water cooled balanced 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 – 701MHz).
Adjustable bandwidth, available for 6, 7 & 8MHz 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.
Multiple probe directional couplers can be added to the input and output for power monitoring.
