T he electron tube 4CX20000C is a high-performance ceramic/metal power tetrode
designed for audio and radio frequency applications. It is particularly well-suited for use in VHF FM broadcast transmitters. It is also recommended for rf linear power amplifier service. The anode dissipation is 20KW with forced-air cooling.
It features a type of internal mechanical structure which results in high rf operating efficiency. Low rf losses in this structure permit operation at full ratings to 110 MHz.
