Presents a comprehenisve description of crystal filters, their features and their limitations, along with detailed descriptions of design procedures for monolithic crystal filters and the hybrid-lattice type of filter. The book simplifies the complex techniques of filter design by following procedures step by step, from a handbook LC ladder filter to a finished crystal filter. Explores fabrication and testing, for those involved in the manufacture and testing of these products, and includes information on specification and applications for those who use them.
