New affordable 6GHz Vector Network Analyzer from MegiQ

Developers of wireless products that need to push to the higher communication bands now have access to an affordable VNA for operation up to 6GHz. The new MegiQ VNA-0460 VNA measures impedances and other S-parameters from 400MHz up to 6GHz.

For many Wireless Devices the Total Isotropic Sensitivity (TIS) can be derived from Total Radiated Power (TRP) together with the transceiver properties.

The MegiQ VNA software has a built-in match calculator. This function now allows for manual adjustment while the software shows the 10dB return loss bandwidth in realtime.

MegiQ introduces a portable, compact Radiation Measurement System that allows wireless developers to measure (antenna) radiation patterns and TRP of their RF device from 700MHz to 4GHz.

MegiQ introduces an Application Programming Interface (API) for their popular series of VNAs. With this API, programmers control the measuring process and data flow to integrate RF testing in production tests or specialized VNA measurements. This makes it possible to implement a very cost-effective solution to S-parameter verification in production testing.

Although a very good design will help to achieve high yield on antenna performance, batch to batch tolerances in PCB and components can suddenly influence resonance frequencies of on-board antennas.
There is an easy way to determine the resonance frequency by wireless without having to probe electrically. Just as with the old grid-dippers

Most VNA manufacturers focus on using the best possible connectors and accessories for test setups: N-connectors, phase stable cables and golden calibration standards. These are so bulky that it is almost impossible to get to a real-life circuit board. On the other end of the spectrum are the small and cheap UFL connectors and cables. Are they suited for VNA measurements and circuit optimization?

Sometimes it is desirable to test or verify the operation of an antenna without physically connecting to it. This can be useful for verifying a series of products, in production, or to avoid disturbing the ground current in its ‘natural’ state. This article describes a technique for measuring antennas without physically contacting it.

Everything goes wireless, also luminaires, mostly using mesh-kind of RF communication for control. There are all kinds of off-the-shelf RF electronics available for the Luminaire Designer. This leaves the Luminaire Designer with a big question mark: “How to design a luminaire for reliable RF communications in the field.”

Connectors can be vulnerable. In your RF test set-up you make use of connectors like SMA, UFL or WFL. These connectors have a limited amount of mating actions, they wear down. Specially in T&M setups, there where you want to be sure of reliably & repeatable connections, you should take good care of connectors
