Abstract :
A novel analysis of feedforward linearizers providing design procedures for determining circuit parameters required for specified linearity and achieving high efficiency, is presented. Experimental results are reported for a C band feedforward linearized amplifier demonstrating a minimum of 20 dB intermodulation distortion suppression across the 5.9-6.4 GHz satellite band.
