What our customers say

"Today we have got already first results, and at the moment we're completely satisfied with the VNA"

Oleksandr Pavlenko, Protelus GmbH.

"The MegiQ VNA is very useful in our production to screen ceramic antennas for their frequency range"

Ivo Mols, Honeywell.

"It is very convenient to work with. I finished the project on 400-465 MHz and 915 MHz and it worked very well. The device paid for itself in a month work."

Dr. Siavash Sheikh Zeinoddin, Calgary University.

"I discovered MegiQ VNAs and it was exactly what we needed."

Professor Luis Ángel Tejedor, Complutense University, Madrid.

"I am very satisfied with the performance of the VNA0440 with Sandbox, the nice and clear documentation. You can get started right away. And everything in a practical and sturdy case with all accessories. Congratulations."

Koen, Belgium.

"...These results demonstrate that MegiQ’s VNAs can deliver performance that is comparable to other VNAs on the market today. ... If you’re in the market for a VNA, don’t overlook MegiQ."

Microwave and RF Magazine

"Sorry to keep bothering you, but your VNA has really unlocked the RF design doors for me."

Lawrence Gorton, Gortronix, Las Vegas.

"I assembled the RMS and also installed the VNA. I am amazed how you guys designed all of it so thoughtfully and elegantly."

Professor Miroslav Joler, University of Rijeka, Croatia.

"The RMS gives us a real insight in the performance of our wireless devices and saves a lot of testing time"

Siebren de Vries, Chess Wise.

"Meanwhile I have shown the VNA-0440e to our RF class, and they like it a lot. We compared its measurements with the R&S and did not notice any differences."

Stefan, Dormakaba, Switzerland

"So far the measurements have been great and I’m really enjoying the simplicity of operation compared to the big R+S equipment!"

Dustin, Silver Bullit, CA

"I've read all your appnotes and I'm impressed by the practical approach."

Peter de Vroome, PNE Benelux

"This unit is great, really excited about the performance I am seeing...Great unit at a very reasonable price point."

Steven, WI

"Thank you, it all worked out! MegiQ rocks!!!"

Stefan Wyss, Dormakaba, Switserland

Measuring Small Antennas

If you have a small PCB with a small antenna you can't use a thick cable and a large connector. Not only is this impractical (how to connect the connector?) but the metal bulk will also affect the antenna and grounding properties of your PCB. The measurement will be useless.

MegiQ promotes the use of the small and popular UFL connector and its associated cables. The UFL socket fits on almost any PCB and it can be improvised on a board without a UFL footprint.

We have created several UFL toolkits that include a calibration kit that matches several PCB stacks. You can also find several UFL application notes on our website.

Our VNAs are also small enough to fit on a lab bench near the device under test.

A great feature in our software is the 'point and match' procedure. You click on a point in the Smith chart and the software will propose several matching circuits. When you select one of them the software wil simulate this match in real-time. With proper calibration the match can be built and the results are often spot-on! Sometimes a small iteration is needed.
