New Microwave Products Expand Your Capabilities

Posted by Brook Sandy on May 15, 2024 8:15:00 AM

At Knowles, we closely monitor the trends and market conditions that impact our customers’ design needs. As a specialty components manufacturer with in-house ceramic and thin film manufacturing expertise, we can quickly adapt to these changing needs to make it easier for customers to find exactly what they are looking for. That’s why in 2023 we released numerous new off-the-shelf DLI brand microwave devices.

These components are made with our temperature stable ceramics, are incredibly small compared to other similar parts on the market, and cover a range of frequency bands, from the S band to the V band. Below is a summary of the capabilities of our latest microwave product offerings.

Exploring the Capacitor Technologies Needed in Electric Vehicles

Posted by Peter Matthews on May 8, 2024 8:14:00 AM

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. When performing these tasks, manipulating AC voltages and removing noise from DC voltage requires passive components such as capacitors, to perform many “jobs” inside the power system. But no single capacitor type can perform all these jobs since each one has different requirements for voltage, size, temperature, and reliability. Therefore, a variety of capacitor technologies, such as ceramic, film, and aluminum, are required to meet all these needs.

The Role of Sensing Technologies in Delivering Personalized Patient Care

Posted by Peter Matthews on May 1, 2024 8:36:00 AM

Sensing technologies facilitate the gathering of detailed and accurate health data that are unique to each individual. The availability of real-time, precise data presents more opportunities for tailored approaches to treatment and care management, aligning medical interventions with specific patient needs. As sensing technologies advance, they enable a more nuanced understanding of individual health patterns, driving innovation in personalized care that aligns with the genetic, environmental, and lifestyle factors of each patient. Here are some key areas where sensing technologies are supporting individualized care.

The Influence of Phase in Filters for Radar

Posted by Peter Matthews on Apr 24, 2024 8:30:00 AM

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). Since then, we’ve covered duplexing, switch filter banks and filters in detail. In this post, we’ll discuss what phase can tell us about filter performance in radar applications.

Examining the Latest Electric Vehicle Technology Trends

Posted by Peter Matthews on Apr 17, 2024 8:11:00 AM

The market demands and technology trends that impact all aspects of electric vehicle (EV) development are constantly evolving. As trends change, so do the requirements for EV power systems, which impacts the demands placed on the components we supply. Therefore, we feel it is our duty to stay on top of shifting EV trends and share what we are seeing with our customers. This blog looks at three key trends impacting EV development that we are currently monitoring around shifting semiconductor development, in-vehicle system integration as a way to control costs, and the evolution of the EV charging ecosystem.
