Abstract:
1. A phase shifting device configured to receive and change the phase of a signal, said phase shifting device comprising at least two transmission line delay elements, said at least two transmission line delay elements comprising a first transmission line delay element and a second transmission line delay element configured to be coupled to said signal; wherein the magnitude of a phase shift imparted to said signal by said first transmission line delay element is not a multiple or a factor of the magnitude of a phase shift imparted to said signal by said second transmission line delay element; wherein the magnitude of a phase shift imparted to said signal by said first transmission line delay element has a value that is based on a first prime number-based adjustment factor; and wherein the magnitude of a phase shift imparted to said signal by said second transmission line delay element has a value that is based on a second prime number-based adjustment factor; and wherein the magnitude of a phase shift imparted to said signal by said first transmission line delay element is equivalent to the product of a base phase shift value and said first prime number-based adjustment factor, and wherein the magnitude of a phase shift imparted to said signal by said second transmission line delay element is equivalent to the product of said base phase shift value and said second prime number-based adjustment factor.
