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 are primarily designed for piezoelectric lines. Ceramic LTP filters for AM series are designed to address the needs of standard AM filtering requirements. These filters are recommended for use in low cost products where economically, efficient designs are critical. The LTP series for AM use is one of the most recommendable intermediate filters, having such distinctive features as high selectivity, high stability, and adjustment-free operation. Additionally its easy matching with IC helps create an easy circuit design.
