＊Above Specifications are subject to change without notice. Reference No.: DS-MSF1425B Rev.: 02E Sheet: ■ GENERAL DESCRIPTION MSF1425B is designed for the magnetron of X -band radar system. The frequency range is fixed <9380 - 9440MHz> and the peak output power is 10.5kW. ■ ELECTRICAL CHARACTERISTICS PARAMETERS MINIMUM TYPICAL MAXIMUM UNITS Heater voltage (note 1) 6.0 6.3 6.6 V Heater current 0.5 0.55 0.6 A Preheat time 60 - - s Peak anode voltage (note 2) 4.4 4.5 4.8 kV Peak output power (note 2) 10.0 10.5 - kW Frequency (note 2) 9380 9410 9440 MHz ■ ABSOLUTE MAXIMUM RATINGS These ratings cannot necessarily be used simultaneously and no individual ratings should be exceeded. PARAMETERS MINIMUM MAXIMUM UNITS Peak anode current (note 3) 2.5 6.0 A Average anode power input - 25 W Duty cycle - 0.001 - Pulse duration 0.05 1.25 μs Rate of rise of voltage pulse - 100 kV/μs Anode temperature - 100 ℃ VSWR at the output coupler - 1.5 : 1 - Notes 1. With no anode input power. No reduction of heater voltage at operating is required. 2. Measured at peak anode current 4.5A. 3. Any overshoot of the anode current is not acceptable. And, sagging waveform of the anode current causes the poor spectrum and the shifting frequency in the pulse since a magnetron current pushing characteristics.
