Efforts were concerned with modifying the existing UHF Y-circulator into a unit which will be suited for mounting in a standard 19 inch relay rack. Emphasis will be placed on compactness and simplicity of operation. Packaging of the entire circulator system was started. All components are being mounted in a standard 19 inch relay rack which measures 47 12 inches high x 22 inches deep. The 3 18 inch co-ax input port for the transmitter connection and the 3 18 inch co-ax output port for the antenna connection are located opposite each other on the outside of the cabinet. The receiver connection is mounted on the front panel. New samples of a non-linear dielectric were measured and found to have characteristics which are suitable for use in a ferroelectric limiter. These results were obtained using a low power RF signal. The application of a high power RF signal will determine the operating characteristics of a limiter using this material. Author
