Dummy Load,electrical 5985-01-502-9151 A specific electrical element or set of electrical elements that are connected together to form a fixed arrangement and used as a substitute load for terminating an electrical circuit. A dummy load contains all the essential electrical characteristics necessary to terminate the circuit but does not function in the same manner as the load which it replaces. Examples are resistors used to replace antennas, batteries, loudspeakers, or the like. Includes single port terminations of twin lead, coaxial and waveguide transmission lines as low power terminations of a section of a transmission system in a specified manner. Includes dummy loads when arranged in a group or bank. Excludes power absorbers. See also LOAD BANK, ELECTRICAL. RFQ
Antenna 5985-01-502-9169 An item consisting of a conductor or a system of conductors specifically designed to radiate and/or receive electromagnetic waves in free space. May include beam-forming devices, drive motors, synchros, radome, and associated mechanical structure. RFQ
Isolator,radio Frequency Reflection 5985-01-502-9303 A device which allows radio frequency energy to pass in one direction with very little power loss, but blocks the flow of energy in the other direction by means of multiple WAVE-polarization or an integral dissipative load. It isolates frequency sensitive circuity from the effects of reflected radio frequency energy resulting from component mismatch. It usually has one or more ports terminated with coaxial connector(s) and/or waveguide flange(s); or other electrical terminations. Isolators designed for internal use in waveguide runs may consist of rods, rings, chips, strips and the like and have no ports or terminations. See also DIPLEXER; DUPLEXER. Excludes CIRCULATOR, RADIO FREQUENCY. RFQ
Attenuator,fixed 5985-00-001-2334 A device for reducing the strength of an alternating current signal by a fixed or predetermined amount, without causing appreciable signal distortion, by maintaining correct impedance match. RFQ
Switch,radio Frequency Transmission Line 5985-01-502-9598 An item specifically designed for mechanically or electronically positioning one or more radio frequency transmission line sections so as to couple it or them to other sections in a radio frequency transmission line system.
