Vector network analyzer makes measurement sweeps from 70kHz to 220GHz
By offering unprecedented frequency coverage, the new VectorStar VNA allows engineers to more accurately and efficiently characterize devices over a much broader range of frequencies to provide accurate device models, thus optimizing the chance for accurate simulations and opportunity to reduce design turns.
Consistently providing the industry’s widest single sweep broadband coverage for improved device modelling is achieved because the VectorStar VNA system incorporates the Anritsu Non-linear Transmission Line (NLTL) millimeter-wave (mmWave) modules. An innovative design allows the 220 GHz probe to connect directly to the mmWave module for accurate, stable on-wafer measurements, thereby avoiding the limits of coaxial connectors at sub-terahertz frequencies.
The 220 GHz ME7838G leverages Anritsu’s proven VectorStar broadband platform’s ability to go beyond traditional boundaries in a single sweep without the need to reconstruct the wafer probe station from 110 GHz to higher waveguide bands. Because of the design, engineers can measure a wide range of circuits on the same wafer without transferring from a coax microwave VNA to coax mmWave VNA or waveguide mmWave VNA. The system reduces measurement time of the entire wafer, improves measurement accuracy of wideband devices by eliminating the need for waveguide concatenation, and delivers wafer probe station cost efficiencies by reducing the number of VNA reconfigurations.
