Load Pull and Noise Measurements Accessories
In an effort to providing complete measurement solutions to our customers, Focus Microwaves has developed, over time, customized accessories, which will make sure a load pull or noise test system will operate as expected.
Tuner based measurements differ fundamentally from other microwave testing, because the devices operate under non-50 Ohm environment.
VNA calibrations are therefore extremely important and, to our experience, TRL (Thru-Reflect-Line) is the best method to use, at least above 3GHz. We have therefore developed a family of TRL calibration kits.
Since load pull is a lengthy test procedure, on the same device, we opted for a manual, instead of an automatic probe station (LPPS).
Further-on, in order to make the iTuner technology available to every tuner user, we developed the iConverter. iTuners are also available with GPIB control.
Because low impedance devices require very low loss test fixtures or wafer setups, we have also developed such fixtures and specialized on-wafer solutions using extremely low loss coaxial bend-lines, and special tuner 3 axis positioners allowing to mount the tuners under 30 or 45 degrees to match the probe angles.
