"C" Terms
CATCHER GRID. In a velocity-modulated tube, a grid on which the spaced electron groups induce a
signal. The output of the tube is taken from the catcher grid.
CATEGORY 3. The ANSI/EIA/TIA-568 designation for 100-ohm unshielded twisted-pair cables and
associated connecting hardware whose characteristics are specified for data transmission up to 16 Mb/s. [EIA568 Bus Description]
CATHODE. In an electron tube the electrode that is the source of current flow. The general
name for any negative electrode. The negative terminal of a forward-biased semiconductor
diode, which is the source of the electrons.
CATHODE BIAS. The method of biasing a vacuum tube in which the biasing resistor is placed in the
common-cathode return circuit, thereby making the cathode more positive with respect to ground.
CATHODE KEYING. A system in which the cathode circuit is interrupted so that neither grid current nor
plate current can flow.
CATHODE MODULATOR. Voltage on the cathode is varied to produce the modulation envelope.
CATHODE-RAY TUBE (CRT). An electron tube that has an electron gun, a deflection system, and a
screen. This tube is used to display visual electronic signals. [CRT Graphic]
CATHODE SPUTTERING. A process of producing thin film components.
CAVITY RESONATOR. A space totally enclosed by a metallic conductor and supplied with energy in
such a way that it becomes a source of electromagnetic oscillations. The size and shape of the enclosure
determine the resonant frequency.
CAVITY WAVEMETER. An instrument used to measure microwave frequencies.
CELL. A single unit that transforms chemical energy into electrical energy. Batteries are made up of cells. [Battery Manufacturers]
CENTER-FEED METHOD. Connecting the center of an antenna to a transmission line which is then
connected to the final (output) stage of the transmitter.
CENTIMETER CUBE. A unit of volume of large rectangular or square conductors. The cross-sectional
area equals 1 square centimeter with a length of 1 centimeter.
