RF attenuators are circuits that reduce the power level of a signal by a certain amount (gain), with little or no reflection. They reduce the output signal with respect to the input and measure the power reduction in decibels (dB).
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 diplexers are three-port frequency-dependent devices that may be used as a separator or a combiner of signals. RF duplexers allow a transmitter operating on one frequency and a receiver operating on a different frequency to share a common antenna with a minimum of interaction and degradation of the different RF signals.
RF power dividers and RF power combiners are circuits that accept input signals and deliver multiple outputs that are equal in phase and amplitude. There are two basic product categories: passive and active.
RF receivers are electronic devices that enable a particular radio signal to be separated from all others being received and converted into a format for video, voice, or data.
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.
RF waveguide isolators and RF waveguide circulators permit a signal to pass in one direction while providing high isolation to reflected energy in the reverse direction. RF waveguide circulators are passive devices with three or more ports.
