High-frequency 100-nF capacitors improve bypass performance in GaN/GaAs amplifiers
Knowles Precision Devices recently announced the release of a new 100nF capacitor within its V-Series of single-layer capacitors. The 100nF is a high frequency, wire bondable single layer capacitor, making it ideally suited for GaN and GaAs amplifier applications where small size and microwave performance are critical. V-Series single-layer capacitors, including the new 100nF, are […]
Powering EVs with silicon carbide
A flyback converter/isolated-gate-driver combo reduces the cost and complexity of implementing SiC FET designs in EV systems. Charlie Ice, Silicon Labs Electric vehicles are pushing the limits of today’s power conversion technology, and the advent of high-power silicon-carbide (SiC) FETs has pushed the envelope even further. The many advantages of SiC FETs allow for higher […]
Radiation-hardened dc-dc power converters based on COTS technology
