Qortek, Inc. SBIR Phase I Award, June 2019

QorTek plans to model, build and test a low frequency transducer design for the 3” sonar countermeasure that can be supplemented with the high frequency channels. This transducer suite will be coupled with the power amplifier design that is based on previous research and development at QorTek. We will address the 3” challenge with a complete system approach that will trade off design parameters between the ceramic, transducer and electronics design. It is planned that the Phase I Base effort will conclude with a FEA model that is validated with a hardware demonstration of the low frequency transducer channel and power amplifier. The Phase I hardware demonstration will validate the feasibility of the base design when coupled with textured ceramic and high frequency SiC based power amplifiers. The Phase I Option will exit having designed and built a prototype of the complete acoustic and power amplifier suite to finalize the baseline design and update FEA and transducer models.
