Anritsu VectorStar ME7838A4 4-port broadband VNA
The Anritsu VectorStar ME7838A4 4-port broadband vector network analyser (VNA) system provides what the company claims is the world’s widest differential broadband sweep from 70 kHz to 110/125 GHz.
It uses the smallest mmWave modules to conduct highly stable and fast measurements when characterising differential devices. The ME7838A4 provides on-wafer and signal integrity engineers with a high level of performance when conducting differential measurements so they have greater confidence in their next-generation communications system designs.
The integrated 3743A mmWave modules use an exclusive Anritsu design that incorporates nonlinear transmission line technology (NLTL), making them much more compact than alternatives and easy to mount on space-limited wafer probe station platens. Additionally, smaller and lighter modules improve overall performance, including raw directivity performance that results in higher calibration stability. Modules are available that can extend the VectorStar ME7838A4 to a 4-port 145 GHz system.
The VectorStar ME7838A4 4-port broadband system uses an internal substrate-mounted source for thermal stability, resulting in highly accurate calibration and measurement stability of 0.1 dB over 24 h. It also features fast measurement speed of 55 ms for 201 points at 10 kHz IFBW.
Users will benefit from mmWave noise floor sensitivity and the mmWave real-time electronic power levelling that eliminates the need for time-lagging software correction tables. Because internal frequency multiplication begins at 54 GHz in the VectorStar ME7838A4 compared to 67 GHz for other 4-port broadband systems, RF cable losses are reduced for improved dynamic range and phase stability.
