Phase and amplitude controlling ICs realized in a low cost standard silicon process are demonstrated. The design of several ICs at S-, C- and X-band has shown that silicon germanium is a strong contender to gallium arsenide where lowest noise figure is not vital. This applies also to the T/R-modules suited for military AESA-radars. The circuits presented in this paper are manufactured by austriamicrosystems...
A mixed signal receiver IC for C-band radars is presented. The design work has been focused on spectral purity and miniaturization. Miniaturization is achieved by minimizing peripheral components and control signals using internal calibration data and temperature compensation tables stored in RAM on-chip. This allows for the packaged chip to be used with a minimum of. The chip is manufactured by Austria...
