Further remarks

Remark:
• mask filter for DAB and T-DMB
• for 1.54 MHz block bandwidth
• with cross coupling (notch function)
• tunable within the whole band 3
• temperature compensated
• DC block
• installation standing
• natural or liquid cooling
1):
The input power of liquid cooled filters must be reduced if installed more than 500 m above sea level.
