4X150A/7034
Radial Beam Power Tetrode

The Svetlana 4X150A/7034 is a compact radial beam tetrode. The 4X150A is intended for Class AB SSB linear RF amplifier service. It is intended for stationary and mobile equipment designs with power amplification at frequencies up to 500 MHz. The 4X150A has an indirectly-heated oxide cathode. The Svetlana 4X150A is manufactured with rugged, all metal/ceramic construction and will withstand severe military environments. Further, the anode is capable of dissipating 250 watts with forced air cooling, and is rated accordingly. These improved characteristics make the Svetlana 4X150A fully equivalent to the 4CX250B.
