4CW30000A
The EIMAC 4CW30000A is a liquid and forced air-cooled power tetrode for rf amplifier and pulse modulator service, It is recommended for radio frequency amplifier service through VHF where a liquid-cooled anode is required. Incorporating a special anode cooling jacket and a rugged thoriated tungsten mesh filament, this tube achieves a very low level of mechanically induced amplitude modulation of the plate current, Low rf losses in this structure permit operation at full ratings to· 110 MHz and at reduced ratings to 225 MHz.
The 4CW30,000A is also recommended for pulse modulator or regulator service, where the hold-off rating is 28 kilovolts. 35 amperes of peak plate current may be obtained in pulse modulator service,
