Perel'muter Translated from Izmeritel'naya Tekhnika, No. 12, pp. 38-39, December, 1960 It is known that the quality of ferrite rectifiers is determined by the losses in the forward (Pf) and in the reverse (Pry) directions. The forward losses usually amount to several tenths of a decibel, whereas the reverse losses exceed 10-15 db. Forward losses are measured by the substitution method. Reverse losses are normally measured by means of a calibrated attenuator~ In experimental work and in production of ferrite rectifiers this method is not always suitable for the following reasons. After placing the ferrite insert between the pole pieces of a permanent magnet and measuring its voltage standing wave ratio and direct loss, it is necessary to extract it and fix in the reverse direction. When the rectifier losses are high a considerable oscillator power output is required, which is not always available; and it is necessary to have an attenuator calibrated for the entire measuring frequency range. The method sometimes used in waveguides of measuring the VSWR with a stationary plunger (dead end) is unsuitable in this case. This is due to the fact that even very small reflections from the rectifier or irregularities in
