High power amplifier is a very significant component in satellite communication and it is very important to analyze its performance according to the satellite application it is used in. Noise power ratio, also known as carrier to inter-modulation noise ratio is an important parameter for analyzing the performance of high power amplifiers. All power amplifiers are nonlinear to some degree. If more than one carrier is received by a single amplifier, mixing or inter-modulation processes will take place. The inter-modulation analysis becomes complex as the number of carriers are increased in the...
