The Tiga device is not merely an instrument—it is a philosophy: control the boundary condition of a nonlinear device in real time . Where passive tuners reflect, Tiga injects. Where mechanical tuners crawl, Tiga flies at nanosecond speeds. For the engineer pushing GaN, CMOS, or InP to their absolute limits—at the edge of the Smith chart and beyond—the Tiga device is the key that unlocks the nonlinear frontier.
