The RFS 6PPXX325E is designed for mask filtering applications associated with DTV television transmission. It is a 6-pole water cooled filter incorporating dual cross coupling to meet the mask requirements.
• 50 kW power rating
• Very compact for easy integration into equipment.
• Very low insertion loss (lowest for this size).
• Highest power rating for size/class.
• Tunable over 470 – 635 MHz.
• Adjustable bandwidth, available for 6 & 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 ºC ambient temperature operation.
• Water cooled.
