Abstract

A new linearisation technique using frequency retranslation for generating an error signal to predistort the input of a nonlinear mixer is presented. Results from a two-tone-test at 920MHz yields a 25dB reduction in the distortion products and also minimal adjacent channel interference was observed with a pi /4 differential quadrature phase shift keying modulated carrier.
