Previous set of "T" Terms and definitions
TUNED CIRCUIT. A circuit consisting of inductance and capacitance that can be adjusted for
resonance at a desired frequency. A circuit that is used as a filter which passes or rejects specific
frequencies. An LC circuit used as a frequency-determining device.
TUNED LINE. Another name for the resonant line. This line uses tuning devices to eliminate the
reactance and transfer maximum power from the source to the line.
TUNNEL DIODE. A heavily doped semiconductor device that has high gain and fast switching
capabilities. See NEGATIVE-RESISTANCE ELEMENT.
TUNNELING. The piercing of a potential barrier in a semiconductor by a particle (current carrier) that
does not have sufficient energy to go over the barrier.
TURN. One complete loop of a conductor about a core.
TURNS RATIO. The ratio of the number of turns in the primary winding to the number of turns in the
secondary winding of a transformer.
TURNSTILE ANTENNA. A type of antenna used in vhf communications that is omni-directional and consists of two horizontal half-wave antennas mounted at right angles to each other in the horizontal plane. Antenna Dictionary
TWISTED PAIR. A line consisting of two insulated wires twisted together to form a flexible line without the use of spacers. Read more Detailed definition.
TWO-DIMENSIONAL RADAR (2D). Measures the range and bearing to a target. Radar Dictionary
TWO-M (2M). Miniature/micro-miniature repair program.
TWO-WIRE OPEN LINE. A parallel line consisting of two wires that are generally spaced from 2 to 6 inches apart by insulating spacers.
TWO-WIRE RIBBON (TWIN LEAD). A parallel two-wire line in which uniform spacing is assured by two wires embedded in a low-loss dielectric.
