Abstract:

The suitability of dielectric waveguide as a transmission medium in data bus applications has been presented in this report. The feasibility of the concepts has been demonstrated through a Model 400 Dielectric Waveguide Data Bus System. The system operates at millimeter-wave frequencies 22 to 30 GHz and has two frequency division multiplexed FDM data channels, each of which can carry data at rates of up to about 10 Mbs. The system demonstrates multi- channel bi-directional data transfer capabilities over a 100 ft dielectric cable. In this report the design features and test results of a tunable bandpass ring coupler are also presented. These couplers are used in the Model 400 System for coupling signals to and from the data bus. In addition to hardware demonstration of dielectric waveguide systems, their concepts have been used to obtain a data bus configuration for a specific aircraft. For this purpose, flight control signals of the YF-16 aircraft were chosen as an illustration. The data bus configuration for this aircraft has been presented in a block diagram form. It shows that the dielectric waveguide system can fully accommodate all the signal flow requirements.
