Typically, RF poweramplifiers drive the antenna of a transmitter. Design goals often include gain,power output, bandwidth, power efficiency, linearity (low signal compression atrated output), input and output impedance matching, and heat dissipation.   Many modern RF amplifiers operate indifferent modes, called classes, to help achieve their design goals. Someclasses are class A, class B, class C and class E. Class D amplifiers arerarely used for RF purposes because they need even higher frequency devices.   Modern RF power amplifiers use solid-statedevices such as bipolar junction transistors and MOSFETs. Although transistorsand other modern solid-state devices have replaced vacuum tubes in mostelectronic devices, tubes are still used in some high-power transmitters   An antenna (plural antennae or antennas),or aerial, is an electrical device which converts electric power into radiowaves, and vice versa.[1] It is usually used with a radio transmitter or radioreceiver. In transmission, a radio transmitter supplies an electric current
