RF terminators are used to absorb energy and prevent RF signals from reflecting back from open-ended or unused ports. They may include light emitting diode (LED) indicators for conditions such as “power” or “busy”, or mount with a heatsink. There are three main types of RF terminators: coaxial, waveguide, and chip. Coaxial terminators terminate coaxial ports, and coaxial terminators terminate waveguide ports. Chip terminators have an integrated circuit (IC) chip form factor. Typically, they are manufactured with thin-film technology. Form factors and mounting styles for other types of RF terminators are described as flanged, board-level, leaded, panel mount, screw terminals, surface mount, stand-alone, and through-hole.
