Abstract
This paper deals with the design of a 41 mc IF strip for color tv, in which inductances and wiring are etched on the same board. Advantages of this method, together with problems encountered and their solution, are covered. It is shown that one of the least expensive and most satisfactory methods of tuning printed inductances is with vanes. Graphs of Q variations with distance from coil and tuning range are presented for both vanes and powdered iron slugs. The problems of shielding the large field of the printed coils and elimination of undesirable ground currents are covered. Performance data and response curves of a representative strip are given.
