Knowles Precision Devices Selected to Support Joint Strike Fighter Program

Posted by Peter Matthews on Oct 14, 2019 9:00:00 AM

As aerospace and defense technology advances, manufacturers need to find ways to incorporate more features without simply making planes larger, heavier, and increasingly more expensive. This is why the size, weight, power, and cost (SWaP-C) is often a driving factor for aerospace and defense companies when awarding contracts to component manufacturers.

How a $5 Capacitor Turned Into a $1 Billion Problem

Posted by Peter Matthews on Oct 2, 2019 3:10:24 PM

In mission-critical applications, additional screening and testing is required to ensure that only the most robust parts make it to the finished product. Preventative measures, like high quality standards, lessen the possibility of failure in the field and minimize the likelihood of astronomical downstream costs.

A Quick Guide to Properly Selecting a Capacitor for MMIC RF Bypassing

Posted by Peter Matthews on Sep 30, 2019 8:26:00 AM

Supply noise creates challenges in RF systems where it can mix with RF signals, impacting signal-to-noise ratios and potentially causing spurious output. Thus, high-frequency monolithic microwave integrated circuit (MMIC) amplifiers with broadband gain need to be protected from RF noise on the supply lines. Avoiding these issues with supply line noise requires RF designers to use a bypass capacitor that provides an efficient path to ground for RF energy on the supply line before it enters a gain stage (Figure 1).

Non-Magnetic Capacitors for Medical Imaging Applications

Posted by Peter Matthews on Sep 18, 2019 10:46:00 AM

Imaging systems account for a significant portion of the medical devices and electronics industry. There is an expanding range of imaging modalities, and one of the most common is magnetic resonance imaging (MRI). MRI equipment uses a strong magnetic field and computer-generated radio waves to create cross sectional images of the body; these images enable health care professionals to investigate and diagnose without the need for an invasive procedure.

Planar Filter Technology for Millimeter Wave Applications

Posted by Peter Matthews on Aug 21, 2019 9:29:00 AM

The advent of fifth generation (5G) communications brings an increased interest in Millimeter Wave (mmWave) technologies. One of the biggest technology challenges engineers face with 5G is how to implement sufficiently high-performance RF filtering in mmWave applications. Given the frequencies involved a distributed element planar approach, such as using Microstrip or Stripline, is often ideal for constructing resonators and filters.
