DRY-AIR SYSTEM. Provides dehumidified air for electronic equipment that is moisture critical.
DRY CELL. An electrical cell in which the electrolyte is not a liquid. In most dry cells the electrolyte is in
the form of a paste. [Battery Manufacturers]
DUAL-GATE MOSFET. A two-gate MOSFET in which either gate can control the conductor
independently, a fact which makes this MOSFET very versatile.
DUAL IN-LINE PACKAGE (DIP). IC package having two parallel rows of performed leads. [IC Package Type Definitions]
DUCT. In interfacility cabling, a conduit, which may
be direct-earth buried or encased in concrete, used to enclose communications or power cables.
DUCTILE. The propagation of radio waves within an
atmospheric duct. Easily drawn out (as to form filaments or wires).
DUCTING. Trapping of an RF wave between two layers of the earth’s atmosphere or between an
atmospheric layer and the earth.
DUMMY LOAD. A dissipative but non-radiating device that has the impedance characteristics of an
antenna or transmission line. Also called ARTIFICIAL LOAD. More information on [Dummy Load]
DUPLEX CIRCUIT. A circuit that permits transmission in both directions.
DUPLEXER. A radar device that switches the antenna from the transmitter to the receiver and vice versa.
DUTY CYCLE. In a transmitter, ratio of time on to time off.
DYNAMIC MICROPHONE. A device in which sound waves move a coil of fine wire that is mounted on
the back of a diaphragm and located in the magnetic field of a permanent magnet.
