SAW Device
SAW Filter for CATV Transmission Pilot Signal Extraction
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).
