RF Tech Tip: BNC Versus Threaded Connectors
The shielding performance of bayonet vs. threaded connectors is measured and some possibly surprising conclusions are drawn. Bayonet connectors – more useful than you might think.
How EMC Shielding is Defeated
If you’re an electrical engineer and consider proper EMC shielding a mechanical only issue, please reconsider your position and keep reading. Proper EMC shielding is both an electrical and mechanical design issue. Thoughtful coordination between the two disciplines is key to successful EMC shielding implementation on most product development projects.
