A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .
Audio stereo power amplifier made by McIntosh The internal view of a Mission Cyrus 1 Hi Fi integrated audio amplifier (1984) [1]. An audio power amplifier (or power amp) amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones.
Jerrold Electronics was an American provider of cable television equipment, including subscriber converter boxes, distribution network equipment (amplifiers, multitap outlets), and headend equipment in the United States.
Mullard Circuits for Audio Amplifiers is a famous book by the Technical Services Department of Mullard Ltd, a British valve manufacturing company. First published in 1959 and then reprinted several times it contained a number of designs by Mullard engineers for high quality audio amplifiers, which were to be used by amateur constructors as well as by manufacturers as the basis for many ...
In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier 's characteristics and performance. The first three classes are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a ...
During the 1970s, the MC-2300 was an expensive piece of audio equipment, with a retail price of $1799 by the time of its discontinuation in 1980. [1] That being said, its outstanding power and sound production quality made it a valued part of many recording studios and although some people prefer the sound of tube amplifiers, the overall greater reliability and freedom from repair of the newer ...
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 measured in kilowatts, and are used in amateur radio.
In very high power transmitters, such as 10 kilowatts and above, multiple IPAs are combined to provide enough drive for the final. An exciter, an even lower power transmitter, provides a similar service to the IPA by driving it; although an exciter usually encompasses other important functions, such as choosing the frequency of the RF.
