VNA can perform up to 220GHz measurements in a single sweep
According to Anritsu, the VectorStar ME7838G broadband vector network analyzer (VNA) is the industry’s first VNA capable of making measurements from 70kHz to 220GHz in a single sweep. This frequency coverage allows engineers to more accurately and efficiently characterise devices over a much broader range of frequencies to provide accurate device models, says Anritsu, to reduce development times.
The VectorStar VNA system incorporates the Anritsu Non-linear Transmission Line (NLTL) millimeter-wave (mmWave) modules. The design allows the 220GHz probe to connect directly to the mmWave module for stable on-wafer measurements without the limits of coaxial connectors at sub-THz frequencies.
There is no need to reconstruct the wafer probe station from 110GHz to higher waveguide bands, says Anritsu. 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, according to Anritsu.
The ME7838G enables engineers to conduct on-wafer measurements that span into the upper mmWave frequencies for more accurate device characterisation.
