Kaney receives SBIR award for US Navy program to develop sonobuoy power amplifier

The U.S. Navy has selected Kaney for the Small Business Innovative Research (SBIR) program to apply advanced power amplifier technologies to the next block upgrade of AN-SSQ/125 sonobuoys.

Under this effort, Kaney teams in Rockford, IL and Dayton, OH will develop a low distortion Class D power amplifier using high-efficiency, high-power density, wide-bandgap semiconductors. Microprocessor-based distortion reduction algorithms and specialized output filtering will be used to meet distortion requirements.

Amplifier design upgrades are required to support a wide range of input voltages, high-bandwidth, high-power, low-distortion and lower volume than the legacy power amplifier. The AN-SSQ/125 sonobuoys are used by the U.S. Navy for anti-submarine warfare operations. AN/SSQ-125 is air launchable from fixed or rotary-wing aircraft. It is also easily deployable from the deck of a surface vessel.

“Our team hasunparalleled experience in advanced technology and manufacturing critical military and aerospace products that will be leveraged for this new product development,” said Jeffrey J. Kaney, Sr., CEO of Kaney.
