Abstract:

This report covers the work performed on the design of SSB and VHF crystal filters in the frequency range of 2 to 30 MC during the fourth quarter. Suitable ten-crystal, two-sction half-lattice models at 2 and 5 MC were fabricated and test results are presented. An equimotional 10-crystal narrow-band filter at 10.5 MC was designed and tested. Further work to develop a firm theoretical basis for a 10-pole 10-zero design possessing finite rejection peaks with equimotional crystal capacitances is in progress and a design procedure with formula is being completed. Additional computations were performed on the ladder crystal filter and new approaches utilizing the analytic design technique were devised. An initial design of the 30 MC third overtone crystal filter is presented. Author
