Latest Trends in Non-Linear Device Characterization and Modelling for 5G Applications


The Focus Microwaves Group comprises Focus Microwaves Inc., Mesuro Ltd., and Auriga PIV Tech Inc. Focus Microwaves is a pioneering engineering company, founded by Dr. Christos Tsironis in 1973 proposing electro-mechanical tuners. Mesuro’s technology is working in the fields of non-linear measurement systems, device characterization, and circuit design. Auriga PIV Tech. Inc. develops and provides pulsed IV/RF characterization systems and bias tees.

In today’s RF/uW industry the design engineers face many technical challenges.  The products on the market offer different solutions and variety of benefits for specific applications.  Whether it be high power device modeling, complex modulated load-pull for wireless applications or extremely high power pulsed IV characterization for automotive applications, the Focus Microwaves offers many advanced technical solutions for both device characterization and modeling.  With recent advances in technology, commercial wireless standards are moving more and more to mmWave frequencies where on-wafer device characterization provides more and more challenges.  The biggest hurdle for passive load-pull at these higher frequencies is the loss between the tuner and the device under test. A new innovative technique is now available to maximize tuning range for on wafer device characterization, allowing for not only high VSWR tuning but harmonic tuning up to 110GHz. Similarly, 5G communication standards require more and more channel bandwidth because of which the need for wideband tuning is continuously increasing.  Wideband impedance tuning is now possible with Focus’s RAPID active loop solution which has 500MHz of instantaneous bandwidth allowing users to perform real time modulated load-pull measurements.
