Abstract
A computer-controlled load pull tuner is embedded in a quarter-circle waveguide-to-wafer-probe adapter and creates a compact and handy assembly. The tuner includes two, along the 90-degree arc of the waveguide, sliding carriages, each holding a tuning probe inserted at fixed penetration without cumbersome vertical axis mechanisms. The carriages holding the tuning probes are spring preloaded against the waveguide wall and can tilt, when hitting a stop, lifting the tuning probes out of the waveguide cavity, thus allowing for a low residual reflection and high transmission behavior. On top of full load pull capacity, the assembly can be used for instantaneous s-parameter measurement when the tuning probes are lifted. High-speed calibration and tuning algorithms allow efficient operation.
