SAW Device SAW Filter for CATV Transmission Pilot Signal Extraction For Industrial Use n Features This filter is used in the pilot signal section of a CATV Repeater. Its narrowband filter characteristics allow pilot signals with fewer spurious waves to be extracted. l Highly reliable. l Low-loss and narrowband characteristics. l Compact (9.1 x 7.1 x 1.6 mm).
