High-energy pulses power some of the most advanced technologies, from high-power radar to medical imaging. But generating a pulse with consistent power isn’t as simple as discharging a capacitor. Pulse Forming Networks (PFNs) are critical for shaping and controlling high-energy pulses. Unlike direct capacitive discharge, which results in a decaying pulse, PFNs create a well-defined, steady output. Choosing the right capacitor is key to PFN performance. Factors like voltage rating, ESR and energy density all impact efficiency. Want to learn more about PFN design and capacitor selection?

From 8,000 feet below the Earth’s surface to 140 million miles away on Mars, our capacitors and microwave and RF devices are used in some of the world’s most complex mission-critical applications.?? ? Watch this short video to learn more about our company and why our high-performance components are trusted to meet even the most stringent requirements.?

Why do capacitors and inductors behave like opposites in RF circuits? Capacitors store energy in an electric field and help regulate voltage changes, while inductors store energy in a magnetic field and resist changes in current. As frequency increases, capacitors allow more current to pass, behaving like short circuits, whereas inductors increasingly resist current flow, acting more like open circuits. This fundamental interaction is key to RF circuit design, especially in LC tank circuits and impedance matching networks. LC circuits form the backbone of RF signal filtering and tuning, ensuring efficient power transfer across components. In this week’s Knowles blog, we cover how these components work together to shape RF performance. https://bit.ly/42fnRSG

Short-circuit ceramic coaxial resonators made with modern high-performance ceramic dielectric materials can offer many benefits over LC resonators in high-frequency applications. Discover why our ceramic coaxial resonators are an ideal option for many applications in the UHF and microwave frequency ranges, especially when cost, size, and stability are important. https://hubs.ly/Q034P7LN0

High-energy capacitor banks power the world’s most advanced pulsed energy experiments. These systems deliver massive, fast-discharge energy for plasma generation, heating, and confinement. Discover how high-energy capacitor banks drive breakthroughs in fusion and beyond: https://bit.ly/3DyqZQc

One question our RF engineers frequently get is, “How is your test data so accurate?” The answer – we have more than a decade of experience designing filters on evaluation boards and comparing that data to both our simulated and test performance data. As a result, we can guarantee customers the performance in our specifications will match what they experience in their applications. Watch this short video to learn more.
