Abstract

In this work, DC bias conditions of active RF power amplifier at 2.4GHz band have been changed and however the effect of the power amplifier to linearity performance has been investigated with the aid of a simulation program. The effect of certain level changes at DC bias conditions to linearity performance parameters such as third order intercept point (TOIP) of the power amplifier, total harmonic distortion (THD), 1dB gain compression point (P1dB) has been investigated. Also, under changing DC bias conditions, not only linearity performance but also parameters of gain and power added efficiency (PAE) of the power amplifier have been investigated and obtained results have been evaluated. Moreover, it has been observed that changing DC bias conditions affect the performance parameters of gain and power added efficiency in addition to the linearity performance of the power amplifier.
