| 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). For Industrial Use Pb Free n Specifications Model Item Nominal frequency : f0 (MHz) 1-dB passband width (kHz) Insertion loss (dB) DC to 445.25MHz Guaranteed attenuation (dB) 445.25 to 448.25MHz 456.25 to 457.25MHz 457.25 to 550MHz Operating temperature range (C) Terminating impedance () min. - f0 25 - 40 25 25 40 WF380A typ. 451.25 - - 50 40 50 50 -20 to +70 290//16nH max. - - 6.0 - - - - n Dimensions mm PAD NO.
