Abstract EN
In this paper, a double loop feedforward linearization technique is analyzed and built with a MMIC low noise amplifier “HMC753” as main amplifier and a two-stage class-A power amplifier as error amplifier.
The system is operated with 5V DC supply at a center frequency of 5.8GHz and a bandwidth of 500MHz.
The proposed technique, increases the linearity of the MMIC amplifier from 18dBm at 1dB compression point to more than 26dBm.
In addition, the proposed system is tested with OFDM signal and it reveals good response in maximizing the linearity region and eliminating distortions.
The proposed system is designed and simulated onAdvanced Wave Research-Microwave Office (AWR-MWO).
