Since there are an impressive number of European Microwave companies engaged in nonlinear device characterization and the development of related test systems, it is appropriate that the European Microwave Week exhibition will feature a sizable representation of companies offering load-pull and related test solutions. Several of these companies were mentioned in last March’s cover story on non-linear Characterization and device modeling including Mesuro, NMDG, AMCAD and Verspecht-Teyssier-DeGroote. Each of these companies has developed the test systems and software for measuring transistor behavior under large signal conditions and generating compact or behavioral models, such as the Cardiff or poly-harmonic distortion (PHD) models. North American companies such as Maury Microwave of California and Focus Microwave of Canada will also be at the show along with the major test equipment vendors that these specialized partner with (i.e. Agilent, Rohde & Schwarz and Anritsu).
And so, just in time for the exhibition, NMDG has just announced the release of their new ICEBreaker application, which provides comprehensive visualization of measurement data sets. This application, which is free, can be upgraded to perform generic sweep plans such as DC, power and/or loadpull sweeps, and to collect measurement data in an accurate way. In addition, the company announced that nonlinear characterization under pulsed DC and pulsed RF conditions is now available in the NMDG ICE software platform, implemented to work with different types of receivers and pulsers.NMDG will be presenting live demos of the NM600 Fast Source and Load Pull under pulsed conditions and of the S-functions model extraction under mismatched conditions using the NM300 ZVxPlus solution this week at Rohde & Schwarz Booth #70 during the conference.
