  • Abstract
    The application of feedforward linearisation to a 950 MHz, 1 W solid state amplifier is described. Results are given for a series of two-tone intermodulation distortion measurements. The effects of amplitude and phase errors in the linearisation circuit are also measured. It is shown that a 25 dB improvement in the intermodulation margin can be achieved over a bandwidth adequate for microcellular radio systems.
