Broadband VNA features single-sweep coverage up to 125 GHz

Anritsu has claimed the first vector network analyzer (VNA) broadband systems with the launch of the VectorStar ME7838AX/EX series systems that offer single-sweep coverage up to 125 GHz (AX)/110 GHz (EX) with guaranteed and typical specifications. The unique capabilities of the broadband VNA systems to sweep and provide characterized data through 125 GHz provide design engineers with the ability to improve their device models for significant improvements in first time yields and performance, said the company.

The VNAs target communication design engineers designing systems for on-wafer applications, and on-wafer production facilities where RF, microwave, and mmWave devices, components, and subsystems need to be measured on the same wafer as well as researchers and manufacturers developing new communications technologies.

Anritsu offers four broadband VectorStar-based VNA models from 10 MHz (optional 70 kHz) to 125 GHz with guaranteed specifications available. With the additional 5 GHz guaranteed frequency sweep compared to previous VectorStar systems, the ME7838AX, ME7838A4X, ME7838EX and ME7838E4X meet the demand for accurate verification of components and broadband applications operating at 122 GHz.

Similar to other VectorStar broadband systems, the VectorStar ME7838AX/EX offers superior time domain analysis using the most points available in a single channel with the widest broadband frequency and best resolution, said Anritsu, along with industry-best millimeter wave (mmWave) noise floor and dynamic range at 120/125 GHz, calibration and measurement stability of 0.05° over 24 hours, and broadband measurement speed of 1 second at 1601 points, 10 kHz IFBW.

In addition, the ME7838AX/EX are compatible with compact, lightweight mmWave modules for easy and precise positioning on the wafer probe station. They are the only mmWave modules compact enough to provide direct connection to on-wafer probes for maximum dynamic range and measurement stability, according to Anritsu. The series also includes the first mmWave module with electronic power leveling to offer the widest power level control of up to 50 dB.

The ME7838AX/EX systems are available in 2- and 4-port configurations. Anritsu provides an upgrade path to existing VectorStar ME7838 broadband system customers.

To support measurements to 125 GHz, Anritsu also introduced the 3656C Series calibration and verification kits that are characterized to 125 GHz. Four versions are available, including with cal. coefficients (.ccf) only and with or without a verification kit. Anritsu also offers .s1p database definitions (and .ccf) calibration kits with or without verification kits.
