In this paper we present the design, characterisation and non-linear control of an analogue pre-distortion (APD) MMIC at E-band. With non-linear behaviour models of the APD MMIC, we demonstrate the capability of controlling the quadrature gain and quadrature third order term. Finally, the APD is com...
