| cpi | 4cx20,000D/ 9015 cpi|4cW50,000J 4cx20,000D/9015 The EIMAC 4CX20,000D/9015 is a ceramic/metal VHF power tetrode intended for use as a RF amplifier up to 110 MHz. It is particularly recommended for use in the 88-108 MHz FM band. It features an electromechanical structure which provides high RF operating efficiency and low RF losses. The 4CX20,000D has a gain of up to 20 dB in FM broadcast service. The anode is rated for 20 kilowatts of dissipation with forced-air cooling and incorporates a highly efficient cooler of new design, which significantly reduces air pressure and flow requirements and produces low acoustical noise. chaRacteRistics Plate Dissipation (Max.)
