Abstract:

Electronic control of phased arrays in the HF region 3 MHz to 30 MHz offer many advantages for RDF systems which make use of such arrays. One of the principal difficulties is that of obtaining a satisfactory device to permit phase adjustment with electronic control. The solid state delay element, which utilizes the minority carrier transport delay of a semiconductor material, is a device which permits a variable phase shift in the HF range over the complete range of 360 degrees. The feasibility of such a device is shown by means of both experimental and analytical work. Author
