An Investigation of Third-Order Intermodulation Distortion in Reflection-type Variable Attenuators M. Chongcheawchamnan and I. D. Robertson Microwave and Systems Research Group, University of Surrey, Guildford, UK Abstract -- The analysis of two-tone third-order intermodulation distortion in the reflection-type attenuator employing FETs is presented for the first time. The validity of the closed-f
