Straight Cut Hermetic Glass to Metal Seal Connectors 50ohm RF Feedthroughs
- 50ohm RF impedance ensures minimal signal reflection and high integrity for superior signal transmission in RF applications
- Straight cut design offers a precise, easy-to-integrate solution with low mechanical stress for stable performance
- Glass to metal seal provides hermetically sealed, leak-proof connections, ideal for use in extreme environmental conditions like vacuum and high-pressure
- RF feedthroughs are optimized to minimize signal loss, ensuring reliable high-frequency signal transmission with minimal interference
- Perfect for high-reliability industries such as aerospace, telecommunications, and defense, where consistent performance is critical
Glass to Metal Hermetic RF/DC Feedthroughs/Seals /Multi-pin Headers /Connector is also called Glass insulator. They are mainly used to transmit microwave signals, power signals and control signals between modules and modules, modules and components with gas sealing requirements. They are one of the most critical components in sealing components. The glass with low dielectric constant and low dielectric loss is used as insulating and supporting material. The housing and conductor is made of Kovar alloy that sintered under high temperature, and the surface is gold plated. The centerconductor has a variety of termination styles such as gold wire bonding, soldering and mating etc. Glass insulators are small, lightweight, hermetic, high reliable and have been widespread in electronics manufacturing industries in recent years.
Structure
Glass insulator is composed of three parts: outer conductor/shell, glass medium and center conductor/pin.Its basic structure is shown in the figure.
