A high-performance X-band triode

A new titanium — ceramic tube is capable of providing up to 100 times the power output of previous triodes in the X-band region. R-f oscillator outputs as high as 4 watts with efficiencies up to 12 per cent are obtainable at 8 gc. The tubes, constructed with built-in tunable output resonators, can be inserted directly across a waveguide, making use of only two bypass capacitors and a contact wire for the grid return
