The electrical power systems in most modern technologies, like electric vehicles (EVs), are complex. In EVs specifically, power systems are responsible for performing many tasks such as converting AC to DC and DC to AC as well as managing changing power levels in DC/DC conversion.

Sensing technologies facilitate the gathering of detailed and accurate health data that are unique to each individual.

This is the fifth installment in our RF Components for Radar series. In the first installment, we provided an overview of the key functional units in radar, including duplexing, filtering, power amplification, waveform generation, low-noise amplification (LNA), receiving and analog-to-digital conversion (ADC).

The market demands and technology trends that impact all aspects of electric vehicle (EV) development are constantly evolving.

At Knowles Precision Devices, we have a long history in radio frequency (RF) and custom discrete passive components. Our rich heritage in variable and trimmer capacitors comes from Voltronics and Johanson and our expertise in High-Q multi-layer ceramic capacitors (MLCCs) is supported by DLI and Syfer.

The developmental trajectory of many modern power electronics systems is driven by evolving carbon dioxide (CO₂) regulations. By maintaining compliance, green energy production, like photovoltaics (PV) and wind, and high-efficiency distribution systems, like high-voltage direct current (HVDC) and battery energy storage systems (BESS), support our transition to a more sustainable future.

In the fourth installment in our RF Components for Radar series we cover how RF filters help radar receivers isolate desired signals, reject interference, and enable high-performance digital beamforming in modern radar systems.

We recently released new supercapacitor modules that provide a significant jump in voltage rating over typical radial-mount supercapacitors, up to 9.0 WVDC.

In other blogs, we’ve talked about inductors in terms of their role in lumped element filters. Here, we’re going to take a step back to discuss inductors and related passive electronic components, including air core inductors and baluns.

In the first installment of our healthcare technology series, we discussed areas where health outcomes are improving as technology shifts closer to patients. Here, we’ll scratch the surface on three trends that are improving medical imaging technologies, and by extension, diagnostics, patient outcomes and access to care.

For the third installment in our RF Components for Radar series, miniaturized switch filter banks help modern radar systems adapt to changing missions and crowded RF environments while maintaining high performance.

At Knowles, it is our mission to provide specialty components that meet even the toughest performance and reliability requirements, especially for applications where failure is not an option.
