It enables simple paralleling of several converters, suffers from no parasitic oscillations and operates with soft commutation of the rectifier diodes.
To avoid parasitic oscillations, this type of a harmonic load pull system must provide high reflection inside the test bandwidth, high tuning resolution, high power handling and low-pass characteristics.
The feedback ratio of [C.sub.06]/[C.sub.07] is high to prevent parasitic oscillations. These parasitic oscillations occur at a distance of 50 to 100 MHz from the targeted oscillation and originate from the external LC resonant circuit.
