Anritsu has established a new standard in broadband performance with the introduction of the VectorStar ME7838D broadband system providing industry-leading frequency coverage of 70 kHz to 145 GHz in a single sweep using a coaxial test port.
The VectorStar ME7838D gives design engineers greater confidence when performing on-wafer device characterization at 70 GHz and beyond with best-in-class dynamic range, calibration and measurement stability, and measurement speed. Applications include 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 conduct a single sweep on a device over multiple RF, microwave, and millimetre wave (mm-wave) waveguide bands, allowing engineers to more accurately characterise devices. Due to the ability of the VectorStar ME7838D to perform sweeps from near-DC to 145 GHz, engineers can create more accurate models and have fewer design turns when devices are subsequently used in applications.
The key enabler for broadband operation to 145 GHz is the Anritsu-developed MA25300A Non-Linear Transmission Line (NLTL) module, which extends the frequency range of previous Anritsu NLTL modules and is compatible with the basic VectorStar ME7838 system. All versions of the ME7838 series, such as the ME7838E 110 GHz system and the ME7838A 110/125 GHz system, can be upgraded to ME7838D 145 GHz performance.
Anritsu’s innovative 0.8mm test port connector is designed for use with the VectorStar ME7838D broadband system. The 0.8mm connector creates new opportunities for advanced network analysis and system design above 110 GHz. By extending the frequency range of broadband measurements to 145 GHz, the VectorStar ME7838D serves as a multiple band system that occupies only one probe station.
In addition to space savings, the VectorStar ME7838D eliminates the need to set up separate broadband and waveguide band systems and concatenate the data from the two configurations, saving time and increasing measurement confidence.
Performance features of the VectorStar ME7838D broadband system include dynamic range of 120 dB at 10 MHz, 110 dB at 67 GHz, 109 dB at 110 GHz and 94 dB at 145 GHz; stability 0.1 dB over 24 hours, resulting in fewer calibrations for increased throughput and lower cost-of-test; and improved throughput from measurement speed of 110 ms for 401 points at 10 kHz IFBW.
