![]() Characterizing the high-performance devices will require new techniques that are well beyond the capabilities of conventional methods being used. To evaluate the performance of these new circuits and components, test circuits employing innovative technologies and components will also be required. Examples of active device technologies include Gallium Nitride (GaN) and graphene and examples of passive components include transmission lines and interconnects, splitters, and hybrid couplers. 1, 2, 5) in order to implement new system capability and to provide characterization testing of the developing new active technology components for use in developing systems. ![]() These new technologies will require innovative passive circuits/components possessing superior performance characteristics (Ref. DESCRIPTION: Current research points toward future electronic warfare (EW), communications (comm) and radar systems operating over very wide bandwidths (1 110 GHz) with circuits employing emerging active device technologies capable of performance substantially beyond the current state of the art. ![]() Materials, design and fabrication approaches will be developed to yield practical passive components and/or innovative characterization techniques, employing photonics or other novel technologies, will be developed for improved characterization of very wide bandwidth, high frequency passive components. OBJECTIVE: The object is to develop practical, low-loss, high-isolation passive components and associated characterization techniques for very wide bandwidth, high frequency (micro- and millimeter-wave) circuit applications.
