A combination of themaximum rating conditions can not be guaranteed.(2) All the voltage parameters are in reference to thecathode voltage.(3) “Vn” is typical filament voltage for average anodecurrent. (see Fig. 4)Filament voltage has to be immediately reducedafter applying the anode voltage, in accordancewith Fig 4.(4) This condition is not drenched by water.(5) It makes used of thermoswitch, which gives opensignal in the case of the temperature greater than80±5 on the tube. Because of magnetron defendsoverheat.(6) Electromagnet data (parallel connection);Re = 4.1 ΩLe = 20 mHDefinition of electromagnet current direction;See Fig 8.(7) See Fig 2.(8) See Fig 3.(9) Waveguide configurationMagnetronE3327WaveguideRF couplerFig 9TaperedWaveguideVariable mismatch(double slug tuner)High powerCirculatoror isolatorLoad
