Microwave Materials
Lossy Dielectrics
Sienna has developed AlN based lossy dielectrics
to replace toxic BeO based components:
• Severes
• Terminations
• Loss Buttons
Sienna's state-of-art STL-100C and STL-150D
materials afford microwave energy absorption,
high thermal conductivity, no outgassing, and
brazeability to copper. Their microwave
dielectric properties can be tailored to meet
your specific requirements. Sienna, through its
strategic alliance with precision machining facilities,
can deliver the exact component you need.

Low-loss Dielectrics
Sienna's low-loss, high thermal conductivity ST-100
and ST-200 AlN are ideal replacements for BeO:
• Collector rods
• Helix support rods
• RF output windows
