Abstract
869,785. Frequency and phase modulation. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Jan. 25, 1960 [Aug.19, 1959], No.28335/59 Drawings to Specification. Class 40(5) [Also in Group XL(b) ] A waveguide section is formed of helically wound metal tape with abutting edges relatively insulated and encloses a ferrite rod whose magnetization is varied by a winding external to the waveguide wall to phase or frequency modulate the transmitted microwaves. The tape may be aluminium, anodized to provide the insulation between turns. The waveguide may be held rigid by a thick external layer of resin. The guide may be formed on a cylindrical mandrel with its ends terminated in planes at right angles to the axis by metal collars whose inner ends are stepped to mate with straight cut off ends of the tape, or the end turns may be soldered together and the waveguide ends cut off co-planarly. Flat faced metal connecting flanges insulated from the guide by the resin layer, may then be secured to the guide ends. The modulating winding may be a few turns of copper tape.
