Generally speaking, solid-state power amplifiers contain four main components: input, output, amplification stage and power supply. [ 8 ] MOSFET transistors and other modern solid-state devices have replaced vacuum tubes in most electronic devices, but tubes are still used in some high-power transmitters (see Valve RF amplifier ).
Solid state linear amplifiers are more common in the 1000-watt range and can be driven by as little as 5 watts. [3] Modern power devices using LDMOS technology allow for more efficient, cost-effective linear RF power amplifiers for the amateur radio community. [4]

The term solid-state became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of ...
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 ...
