L
LINEAR IMPEDANCEAn impedance in which a change in current through a device changes in direct proportion to the voltage applied to the device [12]. |
LIQUIDOne of the three states of matter. It has a definite volume but no definite form (water is a liquid) [1]. |
LIQUID-COOLING SYSTEMSource of cooling for high-heat producing equipments, such as microwave components, radar repeaters, and transmitters [18]. |
LISSAJOUS PATTERNA combined, simultaneous display of the amplitude and phase relationships of two input signals on a CRT [17]. |
LOAD(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 [1] [13]. |
LOAD ENDSee OUTPUT END [10]. |
LOAD ISOLATORA 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 [11]. |
LOADINGSee LUMPED-IMPEDANCE TUNING [10]. |
LOADING EFFECTThe effect of a voltmeter upon the circuit being measured that results in an inaccurate measurement. Loading effect is minimized by using a voltmeter with an internal resistance many times higher than the resistance of the circuit being measured [3]. |
LOBEAn area of greater signal strength in the transmission pattern of an antenna [10] [18]. |
