LT455-450_U-W

For more than two decades, piezo technology has been instrumental in the proliferation of solid state electronics. Traditionally, nearly all low and high-end AM / FM commercial radios use piezo band-pass filters. However, applications are also found in cordless telephones, cellular systems, 2-way communications, and the television industry. As a world leader in the development of piezo technology, Token Electronics has developed specialized piezo materials which when combined with an advance design have resulted in a complete line of practical, low-cost ceramic filters for entertainment and communications applications.

Token ceramic filters for communication LT455/450 U/W series are 4-element and 6-element devices connected in ladder form. These highly selective filters are designed to address the Great Delay Time characteristics required in digital communications. The excellent G.D.T. characteristics allow these filters to be utilized in areas such as the mobile cellular markets as well as a variety of stereo applications. (Also available in 450kHz version.)
