Navigating Capacitor Screening Standards

Posted by Bob Nelson on Aug 14, 2019 9:25:00 AM

Compared to other applications, a medical implant is a rather benign environment for a capacitor; it’s temperature-controlled with a relatively low voltage. That being said, the success of a capacitor in a medical implant relies heavily on manufacturing components to avoid failures and the know-how to screen for any production discrepancies. As the reliability grade of a component progresses, more screening and testing is required to ensure that only the most robust parts make it to the finished product.

RF Filtering Techniques for Millimeter Wave Applications

Posted by Peter Matthews on Aug 6, 2019 3:59:00 PM

The millimeter wave (mmWave) part of the electromagnetic spectrum is at the high end of the microwave region, which spans ~300 MHz to 300 GHz, and is usually taken to mean frequencies from ~30 GHz to 300 GHz and wavelengths in the range of 1mm to 1cm (Table 1). This dramatically increases available bandwidth, thus expanding achievable data rates, which makes these frequencies extremely interesting to teams around the world working on fifth generation (5G) communications.
