Broadband network analyzer covers 70 kHz to 145 GHz in a single sweep

April 15, 2014 // By Christoph Hammerschmidt
With its new VectorStar ME7838D broadband network analyzer, RF test expert Anritsu offers industry-best frequency coverage of 70 kHz to 145 GHz in a single sweep using a coaxial test port. Applications are on-wafer device characterization for 77 GHz automotive radar devices, E-band wireless communication, and emerging applications above 110 GHz.

The VectorStar ME7838D conducts a single sweep on a device over multiple RF, microwave, and millimeter wave (mm-wave) waveguide bands, allowing engineers to more accurately characterize integrated circuits and other RF building blocks. Due to the instrument's ability to perform sweeps from rather low frequencies in the kHz range to 145 GHz, engineers can create more accurate models and subsequently have fewer design turns when devices are subsequently used in applications.

The key enabler for broadband operation to 145 GHz is the MA25300A Non-Linear Transmission Line (NLTL) module. The module, also new in Anritsu's catalogue, extends the frequency range of previous NLTL modules and is compatible with the basic VectorStar ME7838 system. Thus, all versions of the ME7838 series can be upgraded to ME7838D 145 GHz performance.

At the opportunity of the ME7838D roll-out, Anritsu also introduced a novel 0.8 mm test port connector for use with the VectorStar ME7838D broadband system. The 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. Not only does this create 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.

In addition, the vendor introduced the 3739C Test Set for the VectorStar ME7838 series broadband system. The 3739C provides new options for support of antenna measurement systems. The option for antenna measurements is also ideal for other applications in which the mm-wave modules may need to be located up to 5 meters from the VectorStar VNA.
