Abstract

A field effect transistor (FET) quadrature switch for the control of multi mode microwave phase shifters provides bi-directional random mode switching while using only one power supply. The switch apparatus provides high speed, high voltage, and high-current switching while reducing the stand off voltage requirement of the linear driver, the number of switching elements which are required for mechanization, and reducing the size, weight and the complexity of the apparatus.
