Hybrid active Load Pull combines the benefits of both passive and active Load Pull techniques in one setup. Active Load Pull is the only method that allows reaching the low internal impedance of power transistors, especially on wafer and at very high frequencies.
Since 1989 Focus Microwaves manufactures wideband coaxial programmable (slide screw) impedance tuners from 100MHz up to 110GHz. Focus’ fundamental tuners were designed with versatility in mind. The CCMT (Computer Controlled Microwave Tuner) family of tuners have one to three wideband probes enabling very wideband frequency coverage making it ideal for high power applications as well as wideband noise applications.
Non-linear measurement data has been exploited in various ways to create behavioral models for high frequency
components. Formulations of these models have been
defined in terms of traveling waves, with a desire to represent nonlinear behavior of high frequency transistors
through a direct extension from linear s-parameters.
Auriga’s 5th generation pulsed IV/RF characterization system delivers unparalleled performance, capturing measurements with incredible speed and accuracy. Pulsed IV (current-voltage) measurements have emerged as the preferred method of capturing current-voltage characteristics of active devices such as field effect (FETs) and bipolar junction (BJTs) transistors.
