An impedance in which a change in current through a device changes in direct
proportion to the voltage applied to the device .
One of the three states of matter. It has a definite volume but no definite form (water is a liquid) .
Source of cooling for high-heat producing equipments, such as microwave components, radar repeaters, and transmitters .
A combined, simultaneous display of the amplitude and phase relationships of
two input signals on a CRT .
(1) A device through which an electric current flows and which changes electrical energy into another form. (2) Power consumed by a device or circuit in performing its function  .
See OUTPUT END .
A passive attenuator in which the loss in one direction is much greater than that in the opposite direction. One example is a ferrite isolator for waveguides that allows energy to travel in only one direction .
See LUMPED-IMPEDANCE TUNING .
An area of greater signal strength in the transmission pattern of an antenna  .
