    abstract = {Due to good characteristics, unconditional stability, wideband signal capability and high cancellation
of distortions, compared with other techniques, feed forward linearization technique equipped with additional
linearization loop is adopted in this study for linearizing a Class-A RF power amplifier having 5.8 GHz central
frequency. In this study, the adaptation of feed forward technique is employed to improve the characteristics
of a power amplifier for wireless application purposes. The nonlinear characteristics of commercial products are
conditioned using AWR simulation technique to present linearized components for multicarrier transmission
applications. In the linearized product, the third-order intermodulation is reduced to less than (-50 dBc) and the
cancellation of inter modulation distortion approaches 24 dB. In addition for a carrier frequency of 5.8 GHz, an
input signal of a bandwidth of about 125 MHz can be managed with maximum output power exceeding
32 dBm.}
