Anritsu Company will demonstrate what it claims to be the world's only broadband Vector Network Analyzer (VNA) system that can conduct single sweeps from 70 kHz to 140 GHz at the International Microwave Symposium (IMS), in Montreal.

The on-wafer device characterization is one in a series of demonstrations to be conducted in the company's booth that will highlight test solutions for high-frequency designs, including E-band applications and high-speed signal integrity measurements.

A number of higher frequency bands are gaining popularity, including 40-60 GHz for data transmission wireless backhaul between base stations, 60 GHz for Wireless LAN transmission in home and public locations, 77 GHz automotive collision avoidance systems, and 94 GHz for airport radar applications, materials measurement, and homeland security imaging systems.

The demonstration will showcase Anritsu's latest technology, including a 0.8 mm connector, as well as the excellent stability and RF performance of the VectorStar vector network analyzer and mm-wave modules. During the demonstration, the VNA system will sweep from 70 kHz to 140 GHz, highlighting the broadest range of frequency characterization data in a single system. The system will conduct a single sweep across multiple coax and waveguide bands, eliminating the need to use separate systems and associated data concatenation errors.

"Device engineers need broad frequency coverage to accurately characterize devices. To address this need, a connector that can perform above 110 GHz is required," said Bob Buxton, Marketing Manager, General Purpose Test, Microwave Measurements Division. "Anritsu has pioneered high-frequency connectors. We were the first to develop the 40 GHz (2.92 mm) K connector and the 70 GHz (1.85 mm) V connector, and led the way on the 1 mm connector. In order to support a VNA with performance to 140 GHz, we needed to develop and support a new 0.8 mm connector."

VectorStar can also be used for signal integrity measurements, which will be the focus of another demonstration featuring the MP1800A Signal Quality Analyzer (SQA) BERT and MP1825B 4Tap Emphasis. The station will highlight how the best-in-class waveforms and error detector sensitivity of the MP1800A, combined with the ability of the MP1825B to change the emphasis ratio for each tap individually, create a
