Abstract:

Effort was continued in the design and fabrication of preproduction crystal filters. Several new hybrid coils were designed and tested. Minor modifications were included in the final design of the filters in order to reduce passband ripples and to improve the shape-factor. Crystal specifications were finalized and all crystals required for the prototype filters fabricated. Author
