Power Amplifiers can be divided into CW Amplifiers and Pulsed Amplifiers depending upon their application. Further depending upon their output level they are classified as Low Power Amplifiers, Medium Power Amplifiers and High Power Amplifiers. With the advancement of Microwave Integrated Circuit technology and the GaAsFET device technology today highly compact, high performance, low noise power amplifiers for commercial and military applications can be realised to utmost customer satisfaction.
The parameters that characterize, in general, the overall performance of an amplifier are gain, noise figure, gain flatness, output power at 1 dB gain compression point, input / output VSWR, saturation output power, third order intercept point, dynamic range etc. |
