The characterization and modeling of broadband devices presents many challenges, and these become more difficult as new-generation designs move up to millimeter-wave frequencies. When assessing a vector network analyzer (VNA), which is the most commonly used tool, the crucial attributes beyond single-sweep frequency range include stability and uncertainty across the entire measurement band.
A new solution is a broadband millimeter-wave network analyzer, which provides exceptional measurement performance with stability within 0.015 dB and 0.15° over a 24-hour period. Keysight Technologies’ N5290A and N5291A broadband millimeter-wave network analyzers cover a frequency range of 900 Hz to 120 GHz. They leverage the company’s capabilities in terms of metrology and calibration, providing traceable, metrology-grade results across the full frequency range.
