This application note is a collaborative work between Cadence and Rohde & Schwarz and focuses on performance enhancements through linearization of non-linear devices as early as possible in the design process. Using an RF power amplifier (PA) as the reference, we discuss benefits which can be achieved with linearization techniques such as digital predistortion (DPD).
While we bring simulation and RF test of physical hardware closer together, the development process is simplified. More accurate simulation helps to reduce development times and needed hardware iterations for a successful development.
The fundamental challenge for 5G RF front end developers is to ensure proper RF performance with respect to frequency coverage and output power while optimizing energy efficiency. In the development of active components, the first opportunity to investigate your RF design is by testing it right after fabrication of the wafer.
Multi-qubit control, minimizing the error rate, precise characterization of system components – these are major challenges today’s engineers and scientists are facing when designing, building and running a quantum computing system.
A stable frequency source is a common requirement for many electronic and most RF devices. Phase noise is the term used to describe measurements of the short-term frequency stability of these sources. This white paper provides a brief technical introduction to phase noise concepts as well as an overview of how phase noise is measured and reported.
