Broadband IQ Modulator for Rohde & Schwarz#
Due to the fact that test and measurement systems place extremely high demands on the technology that is used, off-the-shelf components are often not up to the task. For this reason, leading test and measurement provider Rohde & Schwarz called on Fraunhofer IIS to develop wideband IQ modulator ASICs that meet the company's special requirements with respect to frequency range, modulation bandwidth, linearity and noise characteristics.
High-Performance RF ASIC as Key Component for R&S SMU200A
This resulted in the development of an 8 GHz IQ modulator ASIC that has been successfully deployed in the R&S SMU200A high-end vector signal generator for many years. Together with Rohde & Schwarz, Fraunhofer IIS developed a successor ASIC based on state-of-the-art, low-cost SiGe technology, which features an extended frequency range of 200 MHz to 22 GHz.
