3D Printed Acoustical Hybrid and Applications Based on the Microwave Case

A common circuit for microwave applications is the 180 Degree Hybrid. A Ratrace hybrid can be implemented in the acoustical case for a 300 mm wavelength; 1.1 kHz for the acoustical case, 1 GHz for the microwave case. The Ratrace hybrid will be characterized. A monopulse array and a linear direction finding array will be investigated. Aspects of 3D printing will be considered.
