Coaxial cables have one conductor insulated with a dielectric material and then surrounded by the other conductor, usually referred to as the center conductor and shield. Triaxial cables are specialized coaxial cables.
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 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.
Telemetry receivers and telemetry transmitters are data acquisition components used to gather information from remote locations via wireless communication.
