Description

Coaxial metal-ceramic tetrode, forced-air-cooled, particularly suitable for VHF satellite transmitters up to 160 MHz/8 kW in grounded cathode circuit with grid-current free modulation. For an easy design of the tuned circuit the control grid terminal is coaxially led out within the cathode terminals. A direct dc blocking of the screen grid produced by the external cathode terminal is thereby
