| GENERAL DESCRIPTION |
![]() |
The 4CM100,000A is a ceramic/metal high power tetrode. It is ideal for use as a plate-and-screen modulated Class C rf amplifier. The tube is characterized by high gain, simplifying drive circuit requirements. Its rugged dense mesh thoriated-tungsten filament provides ample emission for long operating life. The multiphase water/vapor-cooled anode is capable of dissipation in excess of 100 kilowatts. |
