WAFER. A slice of semiconductor material upon which monolithic ICs are produced.
WAFER SWITCH. A rotary switch in which the contacts are arranged on levels. Each level (wafer) is
electrically independent but mechanically connected by the shaft of the switch.
WATT. The unit of electrical power that is the product of voltage and current.
WATTAGE RATING. A rating expressing the maximum power that a device can safely handle.
WATT-HOUR. A practical unit of electrical energy equal to one watt of power for one hour.
WATT-HOUR METER. A meter used to measure electrical energy.
WATTMETER. A meter used to measure electrical power.
WAVE ANTENNA. Same as BEVERAGE ANTENNA. [Antenna Terms]
WAVEFORM. The shape of the wave obtained when instantaneous values of an ac quantity are plotted
against time in rectangular coordinates.
WAVEFORM ANALYSIS. Observation displays of voltage and current variations with respect to time or
by harmonic analysis of complex signals.
WAVEFRONT. A small section of an expanding sphere of electromagnetic radiation that is perpendicular
to the direction of travel of the energy.
WAVEGUIDE. A rectangular, circular, or elliptical metal pipe designed to transport electromagnetic
waves through its interior. [WaveGuide Manufacturers]
WAVEGUIDE DUPLEXER. TR and atr tubes housed in a resonant cavity attached to a waveguide
system.
WAVEGUIDE MODE OF OPERATION. Any particular field configuration in a waveguide that
satisfies the boundary conditions. Usually divided into two broad types: the transverse electric (TE) and
the transverse magnetic (TM) modes.
WAVEGUIDE POST. A rod of conductive material used as impedance changing devices in waveguides.
WAVEGUIDE SCREW. A screw that projects into a waveguide for the purpose of changing the
impedance.
WAVELENGTH. The distance, usually expressed in meters, traveled by a wave during the time interval
of one complete cycle. It is equal to the velocity divided by the frequency.
WAVEMETERS. Calibrated resonant circuits that are used to measure frequency. An instrument for
measuring the wavelength of an RF wave. [Test Equipment Manufacturers]
WAVE MOTION. A recurring disturbance advancing through space with or without the use of a physical
medium.
WAVE TRAIN. A continuous series of waves with the same amplitude and wavelength.
WAVE WINDING. An armature winding in which the two ends of each coil are connected to commutator
segments separated by the distance between poles.
