IVCAD Magic Source Pull

MT930 B/C - Magic Source Pull aka Source Pull Converter, Virtual Source Pull

Applications and Benefits

Combining IVCAD's Vector-Receiver Load Pull measurement methodology in conjunction with AMCAD's patented "source impedance matching method and system" (US patent US8269508B2), Maury Microwave is pleased to introduce MAGIC SOURCE PULL.
  • Eliminate multiple source pull - load pull iterations
  • Improve measurement time per device by 5X or more
  • Analyse higher gammas than achievable with source pull measurements
  • Direct calculation of gain compression vs. performance parameters

Magic Source Pull

Because the a- and b-waves of the DUT are measured at the DUT reference plane, it is possible to measure the large signal input impedance of the device. With this information and through a patent-pending technique, it is possible to simulate the effect of matching the source of the device without having ever varied the source impedance. This "virtual source matching" is highly reliable at even extremely mismatched conditions, and allows for simulated source contours to be drawn. Trade-offs between maximum gain, efficiency and other parameters can be viewed in real-time without multiple source pull load pull iterations.
