What is RF Transistor?

<p>&nbsp; &nbsp; &nbsp; <strong><a href="http://www.upteks-components.com/01-rf-transistor.html" target="_self">RF transistor</a></strong> is a&nbsp;semiconductor&nbsp;device&nbsp;used to&nbsp;amplify&nbsp;and switch&nbsp;electronic&nbsp;signals. It is made of a solid piece of semiconductor material, with at least three terminals for connection to an external circuit. <a href="http://www.upteks-components" target="_self">RF transistor</a>&nbsp;is a variety of transistors, which is differ from other transistor in its maximum operating frequency. A voltage or current applied to one pair of the transistor's terminals changes the current flowing through another pair of terminals. Because the controlled (output)&nbsp;power&nbsp;can be much more than the controlling (input) power, the transistor provides&nbsp;amplification&nbsp;of a signal. Today, some transistors are packaged individually, but many more are found embedded in&nbsp;integrated circuits.</p>

<p>&nbsp; &nbsp; &nbsp; The transistor is the fundamental building block of modern&nbsp;electronic devices, and is ubiquitous in modern electronic systems. Following its release in the early 1950s the transistor revolutionized the field of electronics, and paved the way for smaller and cheaper&nbsp;radios,&nbsp;calculators, and&nbsp;computers, among other things.</p>

<p>&nbsp; &nbsp; &nbsp; The transistor is the key active component in practically all modern&nbsp;electronics, and is considered by many to be one of the greatest inventions of the 20th century. Its importance in today's society rests on its ability to be&nbsp;mass produced&nbsp;using a highly automated process (semiconductor device fabrication) that achieves astonishingly low per-transistor costs.</p>
