VNA features frequency coverage from 70kHz to 110GHz

The new VNA provides on-wafer and signal integrity engineers with a new level of performance when conducting differential measurements so they have greater confidence in their next-generation communications system designs.

The integration of the 3743A mmWave modules is a key feature. Utilising an exclusive Anritsu design that incorporates nonlinear transmission line technology (NLTL), the modules are much more compact than competitive alternatives, for easy mounting on space-limited wafer probe station platens.

Additionally, smaller and lighter modules improve overall performance, including superior raw directivity performance that results in superior calibration stability. Modules are available that can extend the new VNA to a 4-port 145 GHz system.

The analyser’s 4-port broadband system uses an internal substrate-mounted source for excellent thermal stability, resulting in industry best calibration and measurement stability of 0.1dB over 24 hours. It also features a measurement speed of 55ms for 201 points at 10kHz IFBW.

Engineers benefit from unparalleled mmWave noise floor sensitivity and the industry’s only available mmWave real-time electronic power leveling that eliminates the need for time-lagging software correction tables. Because internal frequency multiplication begins at 54GHz in the VectorStar ME7838A4 compared to 67GHz for other 4-port broadband systems, RF cable losses are reduced for improved dynamic range and phase stability.
