A Comprehensive Guide to Our Build-to-Print Services and Thin-Film Technology

Posted by Tim Bice on Aug 11, 2021 9:00:00 AM

At Knowles Precision Devices, we are not trying to be your typical commodity component manufacturer. We want to do things that are hard and help customers solve their most difficult engineering challenges. This is why over the past three decades we have focused on manufacturing high-frequency, high Q components that can function reliably, even in the most demanding applications. Additionally, since every application has different needs, we offer a wide-variety of off-the-shelf catalog solutions, build-to-print services, and even the ability to work closely with customers to create custom thin-film solutions.

Knowles Acquires IMC to Expand Filtering Offering from the VHF to Ka Bands

Posted by Dan Gaffney on Aug 4, 2021 9:00:00 AM

We are pleased to announce that the Knowles Corporation recently acquired Integrated Microwave Corporation (IMC), a leader in the design and manufacture of custom precision RF microwave filters and multiplexers for the aerospace, defense, and communications industries. With this acquisition, the Knowles Precision Devices Microwave group can now offer a complete range of RF and microwave filtering solutions that support applications from the VHF to the Ka band. In addition to the small, temperature-stable filters our customers have come to know us for, we can now deliver ceramic and cavity filters for lower frequency and/or higher power applications. The full range of the IMC filter technologies we now offer is shown in the graphic below.

Fully Digital Beamforming – An Excellent Option for Emerging Military Applications

Posted by Peter Matthews on Jul 14, 2021 9:00:00 AM

As early adopters of beamforming technology in the 1960s, aerospace and defense organizations have a lot of experience using the initial large-scale active electronically scanned arrays (AESAs) for military radar tracking applications. But these arrays aren’t as convenient for some applications today as the operational frequencies of the targets of interest for many military applications are increasing. This means the wavelengths of the signals that need to be monitored are getting shorter and these radar applications need denser arrays since antenna spacing needs to be set at one half the wavelength. For example, at 25GHz, the wavelength in free space is approximately 12mm (0.47”), leading to half-wave spacing for antennas of 6mm (0.24”). Also, as arrays become denser, the new challenge for RF system designers is avoiding interference in these tighter spaces, especially when transmitting signals.

Webinar: Addressing Filtering Challenges in Digital Broadband Receivers for Electronic Warfare Applications

Posted by Tim Brauner on Jun 30, 2021 9:00:00 AM

Today, electronic warfare applications need to detect a wide variety of signals ranging from UHF communications to GPS and other data signals in the L band to high-frequency radar signals that can fall in the X, S, or K bands. Therefore, these receivers need to operate across an extremely wide range of bandwidths to pick up and understand signals anywhere from 300MHz to 20GHz and beyond. However, a basic general wideband antenna isn’t sufficient for these applications because selectivity is needed to determine what you are actually listening to. Additionally, as if the task of designing an ultra-wideband receiver with selectivity wasn’t challenging enough, RF designers are simultaneously facing pressure to reduce the size, weight, and power (SWaP) of these applications as well.

Detonation Capacitors and EFI

Posted by Victor Lu on Jun 23, 2021 8:00:00 AM

Explosives are dangerous by design. For applications involving detonation, like munition and down-hole exploration, explosives should be built to avoid unintentional or premature detonation caused by any rise in temperature or shock. These applications require a number of specialty components including capacitors that discharge high energy at temperatures up to 200°C.
