Svetlana 4CX350A/8321
Radial Beam Power Tetrode

The Svetlana 4CX350A/8321 is a compact radial beam tetrode with a plate dissipation rating 350 watts. The 4CX350A 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 tetrode is of metal-ceramic construction and is designed specifically for severe military environments. The 4CX350A has an indirectly-heated oxide cathode and a forced-air cooled external anode.

The Svetlana 4CX350A/8321 is manufactured in the Svetlana factory in St. Petersburg, Russia, and is designed to be a direct replacement for the equivalent tetrode manufactured in the United States, England and elsewhere.
