Notes
- All Flanges will have clear holes.
- The electrical specifications are for 10% of their respective bandwidths. Wider bandwidths are available at a level of degraded performance.
- Other configurations and specifications are available upon request. Contact us with your requirements. Microtech High Power Pressure Windows are used where it is desirable to isolate a section of transmission or a component, to increase power handling capacity, or prevent foreign material from entering the transmission line.
Our pressure windows employ a high grade quartz window set in a kovar frame. These materials are thermally equivalent for the use in high temperature situations. All high power windows are hermetically sealed.
