Grid bias — is a DC voltage applied to electron tubes (or valves in British English) with three electrodes or more, such as triodes. The control grid (usually the first grid) of these devices is used to control the electron flow from the heated cathode to… … Wikipedia
grid — n. 1 a framework of spaced parallel bars; a grating. 2 a system of numbered squares printed on a map and forming the basis of map references. 3 a network of lines, electric power connections, gas supply lines, etc. 4 a pattern of lines marking… … Useful english dictionary
Cathode bias — In order for a vacuum tube (or valve) to operate in a fairly linear region of its characteristic curve, the grid element must be maintained at a bias voltage more negative than the cathode. This is called cathode bias.Early techniquesEarly… … Wikipedia
IC power supply pin — Almost all integrated circuits (ICs) have at least two pins which connect to the power rails of the circuit they are installed in. These are known as the IC s power supply pins. However, the labeling of the pins varies by IC family and… … Wikipedia
Vacuum tube — This article is about the electronic device. For experiments in an evacuated pipe, see free fall. For the transport system, see pneumatic tube. Modern vacuum tubes, mostly miniature style In electronics, a vacuum tube, electron tube (in North… … Wikipedia
Radio transmitter design — In plate modulation systems the voltage delivered to the stage is changed. As the power output available is a function of the supply voltage, the output power is modulated. This can be done using a transformer to alter the anode (plate) voltage.… … Wikipedia
Linear amplifier — A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio frequency (RF) power amplifier, some of which have output power… … Wikipedia
Inductive output tube — The inductive output tube or IOT is a variety of vacuum tube which evolved in the 1980s to meet increasing efficiency requirements for high power RF amplifiers. The primary commercial use of IOTs is in UHF television transmitters, where they have … Wikipedia
Battery (vacuum tube) — In electronics, vacuum tubes were traditionally powered by batteries. Each battery had a different designation depending on which vacuum tube element it was associated with.Initially, the only such device was a diode with only a filament… … Wikipedia
