Краткое описание:
MAGNETRON 2M248 Series
Дополнительная информация
Toshiba 2M248 series is a fixed frequency continuous wave magnetron intended for use in microwave cooking appliances. The average output power is 1030 watts to a matched load at 330 mA anode current in the frequency range from 2450 to 2470 MHz. The tube is a packaged magnet type and requires forced air cooling. The output is fed either into a rectangular waveguide or into an oven cavity directly.
