power short-wave transistor
11Fluorescent lamp — A fluorescent lamp or fluorescent tube is a gas discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light.Unlike… …
12Timeline of radio — The timeline of radio lists within the history of radio, the technology and events that produced instruments that use radio waves and activities that people undertook. Later, the history is dominated by programming and contents, which is closer… …
13Surface-mount technology — (SMT) is a method for constructing electronic circuits in which the components (SMC, or Surface Mounted Components) are mounted directly onto the surface of printed circuit boards (PCBs). Electronic devices so made are called surface mount… …
14History of radio — The pre history and early history of radio is the history of technology that produced radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio.… …

16Regenerative circuit — The regenerative circuit (or self regenerative circuit) allows an electronic signal to be amplified many times by the same vacuum tube or other active component such as a field effect transistor.Description Regenerative circuits were employed in… …
17Positive feedback — Alarm or panic can spread by positive feedback among a herd of animals to cause a stampede. Positive feedback is energy taken from the output of a system and reapplied to the input, which is phase congruent with the input signal. A system… …
18Indium gallium arsenide — (InGaAs) is a semiconductor composed of indium, gallium and arsenic. It is used in high power and high frequency electronics because of its superior electron velocity with respect to the more common semiconductors silicon and gallium arsenide.… …
