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 180 DEG phase bit is provided by two series diodes with three transmission line segments shunting each junction to ground through a common shunt diode. Operation is effected by the simultaneous forward or reverse biasing of the series and shunt diodes, thereby introducing a 180 DEG phase difference in a signal transmittal therethrough. |
