Compact, solid-state pulse modulators for high power microwave applications

Diversified Technologies, Inc. (DTI) has successfully developed and demonstrated a highly efficient and reliable new approach to solid state switching that can be used in a wide range of high power microwave systems. Switches using this approach are shown in Figure 1 and Figure 2. [GRAPHICS] Multiple switch modules can be combined in series and parallel to meet a wide range of power switching requirements. This paper describes how these switches have been used as replacements for vacuum switch tubes in a Navy radar modulator design, and incorporated into fully solid state modulators and power supplies for high power RF tube testing.
