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. A suitable ten crystal, two-section half-lattice design was syn thesized and models at 2 and 5 MC were fabricated. The 2 MC filter meets the requirements of SCL- 7691A except for its volume, which is 3 cubic in. The 5 MC requires further effort to achieve the required shape factor of 1.4:1. Additional com putations were performed on the ladder crystal filter design presented during the second quarter. A new analysis under different initial assumptions was also performed and some computations made. (Author)
