The KO-Switch™ is the highest power semiconductor switch of its size with a sub-nanosecond response time. Applications include electric circuit protection, pulsed power, ultra wideband (UWB) radar, and arbitrary waveform generation (AWG).

The KO-Switch™ utilizes a specially tailored version of Kyma’s bulk semi-insulating GaN, KO-GaN™, which supports high blocking voltage and low on-resistance. Kyma’s KO-GaN™ materials are grown by a patented and proprietary process based on hydride vapor phase epitaxy (HVPE) and are designed to be highly resistive in the dark yet highly conductive when properly illuminated.
