RS3026CL

The RS3026CL is a RF power triode designed for industrial applications. This tube uses a coaxial design and metal-ceramic technology. This triode may be operated in CW or pulse modes. For operation in pulse mode, the parameters depend on each equipment characteristics. Contact us for specific information. The RS3026CL is a water cooled triode.
