TIMING EXTRACTION FILTER (50 to 300MHz)
F4 SERIES
s DESCRIPTION
The F4 series are timing extraction filter used in the high-grade digital transmission equipment like wide-band ISDN. The F4 series uses a single lithium tantalate piezoelectric crystal (LiTaO3) that has large electromechanical coupling coefficient, and a unique SAW resonator. That provides wide bandwidths, insertion loss, and exceptional stability in VHF band until 300MHz.
s FEATURES
• • • • Wide frequency range: 50 to 300MHz Wide band width: 0.3 to 1.
