The VectorStar ME7838D broadband vector network analyzer provides broadband frequency coverage from 70 kHz to 145 GHz in a single sweep using a coaxial test port. This vector network analyzer has an excellent dynamic range, calibration, measurement stability and measurement speed. It enables design engineers to perform on-wafer device characterization at 70 GHz and beyond, including applications such as 77 GHz car radar, E band wireless communications, 94 GHz remote sensing and airport radar, as well as emerging applications above 110 GHz.
