Category: RF/EMI Shields

When it comes to variables that influence the performance of an RF shielding enclosure, the selected material is at the top of the list. It either absorbs or reflects EMI radiations, ensuring the device is immune to radio frequency interference. Your RF shielding material should be based on your application’s specifications and performance needs. The…

Electromagnetic interference can always pose a threat to microwave/RF designs. Leaks can cause stray electromagnetic energy to impede other circuits, ultimately affecting a microwave’s overall performance. There are two main approaches for microwave shielding: board level shielding and machined housings. Both effectively reduce or block EM emissions before they reach sensitive circuits. Board Level Shielding…

With today’s electronic devices becoming smaller and smaller, there is a greater need for enclosures and shapes that can accommodate those market demands. Board level shielding effectively reduces or limits the effect of electromagnetic interference (EMI) while offering more flexibility as compared to traditional shielding. Design Flexibility Traditional shielding is generally square or rectangular in…

  Electromagnetic interference (EMI), also called radio-frequency interference (RFI), is a disturbance produced by an outside source that affects an electrical circuit due to electromagnetic induction, coupling or conduction.  EMI/RFI shielding is designed to protect electronic devices from malfunction by blocking unwanted external electromagnetic waves or preventing internal electromagnetic waves from emitting and interfering with…

As the rapid spread of the novel coronavirus sent people inside for safety, something came out to clean up the mess: drones. While humans couldn’t interact with one another, drones took over some roles to help people in the midst of the worldwide pandemic. enforcing social distancing While the pandemic resulted in strict stay-at-home orders…

  It’s hard to remember a time where streets were void of electric and hybrid vehicles. In fact, it’s quite common these days to see plug-in stations in parking lots and hear of well-known automotive brands embracing the electric culture.

  Radio frequency interference, or RFI, takes on many forms. It could be a humming microwave that causes a Wi-Fi connection to waver, or perhaps the sounds of a cell phone transmitter traveling through the airwaves of your car stereo.

  Many devices around us have the ability to collect intelligent data about our day-to-day lives. Personal computers store records of the websites you’ve visited; smartphones can keep tabs on your location; and GPS trackers monitor the routes you travel while on the road.

  When radios first made their debut, noise interruptions—from pops and bangs to more subtle disruptions—were all chalked up to being part of the listening experience. But as electronic systems began to appear in military applications, the impact of electrical interference on the operation of equipment and the potential to set off false triggers evolved…

  From simple consumer devices to cutting-edge aerospace equipment, all electronic devices share the electromagnetic spectrum. In close proximity, these devices readily interfere with each other’s performance. Radiated interference (RFI) travels via radio waves, and conducted interference occurs due to the magnetic fields generated by power and data cables.
