A high linearity mixed signal down converter IC for C-band radar receivers

Abstract

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 Microsystems in their 0.35µm SiGe-BiCMOS process and utilizes digital IP-block included in the design kit.
