Design techniques for GaAs MMIC mixers

摘要

Linear single function GaAs MMICs are now a well establishedntechnology. The demand for increased packing density and multifunctionnoperation requires the establishment of, among other aspects, reliablenmixer design techniques. The authors report on the development ofnnonlinear device models and their application to the design of anselection of MMIC mixers and associated linear components. Test resultsnfor these circuits are also given. In all cases the standard Plessey F20nMMIC process was used to realise the circuits
