The VectorStar ME7838D, which also offers best-in-class dynamic range, calibration, and measurement stability, gives design engineers greater confidence when characterizing on-wafer devices at 70 GHz and above, 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.
The VectorStar ME7838D can perform a single sweep of a device across multiple RF bands, including microwave and millimeter waves, enabling engineers to more accurately characterize devices. Because the VectorStar ME7838D can sweep from near DC to 145 GHz, engineers can create more precise models and reduce the number of design cycles when the devices are subsequently deployed in applications.
The key element for broadband operation up to 145 GHz is the MA25300A NLTL (Non-Linear Transmission Line) module. This new module extends the frequency range of Anritsu's previous NLTL modules and is compatible with the basic VectorStar ME7838 system. This allows all versions of the ME7838 series, such as the 110 GHz ME7838E and the 110/125 GHz ME7838A systems, to be upgraded to achieve the performance of the 145 GHz ME7838D.
Anritsu has also designed an innovative 0.8 mm test port connector for the VectorStar ME7838D Broadband System. This 0.8 mm connector opens up new opportunities for advanced network analysis and system design above 110 GHz. Extending the frequency range of broadband measurements up to 145 GHz, the VectorStar ME7838D functions as a multi-band system that occupies a single test station. This not only saves space but also eliminates the need to configure separate broadband and waveguide band systems and concatenate data from both configurations, resulting in significant time savings and increased measurement confidence.
The VectorStar ME7838D wideband system has a dynamic range of 120 dB at 10 MHz, 110 dB at 67 GHz, 109 dB at 110 GHz, and 94 dB at 145 GHz. Its stability is 0.1 dB over 24 hours, reducing the number of calibrations required for increased throughput and lower testing costs. Performance is further enhanced by the VectorStar ME7838D's measurement speed of 110 ms for 401 points at a 10 kHz mid-frequency bandwidth.
Anritsu has also developed the 3739C test suite for the VectorStar ME7838 broadband system. The 3739C provides new options for supporting antenna measurement systems. This antenna measurement option is also ideal for other applications that may require millimeter-wave modules located up to 5 meters from the VectorStar vector network analyzer.
