Abstract
The use of electronically variable phase shifters is required in phased array radar systems. Diode phase shifters are particularly well suited for use in phased array radar systems because they have size and weight advantage over other types of phase shifting components such as ferrite devices and traveling wave tubes and, in addition, offer the potential of cost reductions through the application of batch processing techniques. In accordance with the present invention, a phase bit is provided by the appropriate forward or reverse biasing of one series and one shunt diode to switch between a .pi. circuit and a loop transmission line circuit shunting the equivalent capacitance of the series diode when reverse biased.
