EMI and RFI shielding includes coatings, gaskets, enclosures, sealants, resins and other products or materials that block out electromagnetic interference (EMI) and radio frequency (RF) interference.
RF couplers are circuits that sample RF transmissions by combining (coupling) signals asymmetrically. There three basic types of devices: unidirectional, bidirectional, and dual directional.
RF waveguide components are circular, elliptical or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide.
