Modular Transducer Amplifier (MTA)

Modular Transducer Amplifier (MTA)

Our Modular Transducer Amplifier (MTA) is a high-speed Class-D switch-mode power amplifier specifically designed for applications in underwater acoustic and piezoelectric transducer applications. The MTA utilizes state-of-the-art wide-bandgap Silicon Carbide (SiC) power components combined with QorTek’s proprietary FPGA modulator and control architecture to enable industry-leading power density and system modularity.  The MTA was designed to enable both wideband magnetically coupled and direct-drive applications.
