Product and environmental safety - toxic materials
This product contains beryllium oxide. The product is entirely safe provided that the BeO slab is not damaged.
All persons who handle, use or dispose of this product should be aware of its nature and of the necessary safety
precautions. After use, dispose of as chemical or special waste according to the regulations applying at the location of
the user. It must never be thrown out with the general or domestic waste.
p
Interdigitated structure; high emitter efficiency
Diffused emitter ballasting resistors providing excellent
current sharing and withstanding a high VSWR
Gold metallization realizes very stable characteristics
and excellent lifetime
Multicell geometry gives good balance of dissipated
power and low thermal resistance
Input and output matching cell allows an easier design
of circuits.
