In a world that is constantly expanding wireless communications, the integrity of the
RF/millimeterwave frontend is a cornerstone to the functionality of these systems. Oscillators are a key component in the signal chain in order to modulate carriers to a high frequency for transport from one antenna to another. While there are many types of oscillators, voltage-controlled oscillators (VCO) are very often employed in these circumstances. Due to the prevalence of VCOs, robust test equipment is needed to effectively characterize these components. Rohde & Schwarz offers a number of phase noise analyzers that simplify the verification of VCOs in even the most demanding applications.
This white paper discusses the importance of VCOs, the impact of phase, and how to successfully test these devices from the L band all the way up to the D band for advanced 6G applications.
