Mesuro is working with Tektronix and has developed a high performance active load pull system that simplifies and speeds up the measurement and characterization. This lead me to check out the load pull companies such as Maury and Focus. Maury has added a high power capability so you can test X-parameters at up to 25 or 50 Watts and impedance can be a variable now. They have drag and drop capability for file import into ADS. Focus has also improved their system greatly with the measurements made before the tuners so calibration only has to be performed once and the results are more accurate.
A group of companies including Anritsu, AWR, HFE, Mesuro, NMDG, R&S and Tektronix have joined to create the Openwave Forum. The alliance seeks to standardize the data format for the industry so that customers have the choice of tools, equipment and vendors to use. You can visit their web site at http://www.openwaveforum.org/.
There is a lot of information out there on these new techniques and models so we hope to bring you future articles and information that will sort it all out. Our March Test and Measurement issue will also cover the subject in detail.
Manufacturers are using Accel-RF’s equipment to prove intrinsic reliability and performance degradation characteristics of GaN technology on discrete devices and lower power MMICs. The next stage in the development of the technology is to build and test high power devices for use in radar and military and communication electronics. The new system is either liquid or air cooled, has RF and DC pulsing capability, and can handle device power dissipation of up to 200 watts each. The system is very compact and can now test devices up to 60 GHz. I was very impressed with its capabilities.
We broke up into small groups for the tours with headsets (wireless) that receive the guide's narration as there are many groups around as you walk through. We ended in the Sistine Chapel and then made our way out into the garden. After, we sat inside the Vatican for a beautifully catered dinner. Paolo Lampariello, General Chairman of EuMW, welcomed everyone and challenged next year's chair to top his event with perhaps a visit to the Louvre in Paris. Could be a great opportunity to attend the gala next year!!!

In quickly looking through the sessions, there seems to be much more about higher class amplifiers (Class E and F including inverse versions) as the demand for more power/efficiency increases and the characterization techniques improve. It will be interesting to hear the details about power amplifiers that are over 75% efficient! There also seems to be more CMOS based devices as Si is ever improving its upper frequency limits and of course, more about GaN amplifiers. The passive devices are always getting smaller and doing more functions than their previous generations.
The exhibition starts tomorrow and the setup is nearing completion. The exhibition hall is well laid out and just the right size for this type of show. The large test and measurement companies dominate the entrance with Agilent, Rohde & Schwarz and Anritsu present with large booths. Of course, the component and software companies are well represented along with the large Italian defense companies Electtronica/Selex and Finmeccanica providing a large sponsorship which we don't typically see at the other European locations. It is nice to see such good local support - maybe they can continue in the other locations.
Let me know your impressions of the conference and exhibition.
