Abstract:

The inductively coupled lattice equivalent was found both theoretically and experimentally applicable to the construction of the VHF wideband crystal filters specified by the contract. A step by step design procedure is illustrated. A complete description of the filter including component values and test equipment is given all the test data are presented. The experimental results of a filter with crystals exhibiting spurious manifestations are compared with the results of a theoretical study. The behavior under high drive of a crystal filter is investigated theoretically and experimetally. Methods of measuring crystal parameters and simple tuning procedures are described. Author
