RETENTIVITYThe ability of a material to retain its magnetism [1]. | |
RETURNThe RF signal reflected back from a radar target; echo [18]. | |
REVERBERATIONThe multiple reflections of sound waves [10]. | |
REVERSE AGCThe type of AGC that causes an amplifier to be driven toward cut-off [17]. | |
REVERSE BIASAn external voltage applied to a diode or semiconductor junction to reduce the flow of electrons across the junction. Also called BACK BIAS [7] [13]. | |
RF AMPLIFIERRF (RADIO FREQUENCY) AMPLIFIER—An amplifier designed to amplify signals with frequencies between 10 kilohertz (10 kHz) and 100,000 megahertz (100,000 MHz) [8]. | |
RF RADIATION HAZARDA health hazard caused by exposure to electromagnetic radiation or high- energy particles (ions). Abbreviated RADHAZ [18]. | |
RF TRANSFORMERRF (RADIO FREQUENCY) TRANSFORMER—A transformer specially designed for use with RF (radio frequencies). An RF transformer is wound onto a tube of nonmagnetic material and has a core of either powdered iron or air [8]. | |
RGKThe symbol used to express the resistance between the grid and the cathode of an electron tube [6]. | |
RHEOSTATA variable resistor used for the purpose of adjusting the current in a circuit [1] [4]. | |
