ABSTRACT:
A phase shifter using digital counters allows extremely accurate phase shifts. In a parallel circuit arrangement of a number of basic phase shift units, which each includes a dual modulus counter and phase control circuitry for controlling the counter modulus, the outputs of several units are combined in parallel. With the divider ratios of all the dividers of the units consisting of roots of pairwise relatively prime numbers, the total number of phase states is equal to the multiplication of its divider ratios.
