Description

Coaxial metal-ceramic tetrode, forced-air-cooled, particularly suitable for FM transmitters in ground- ed cathode circuit. 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 possible. This arrangement of the terminals also prevents cross
