Ideal Vacuum Feedthroughs SMA Coaxial Feedthrough, 50 Ohm Matched Impedance, 1 Pin, Floating Shield, Double-ended 1.285 Dia SS Weld Adapter, Without Air-side Connector, Coaxials

The Ideal Vacuum Feedthroughs SMA Coaxial Feedthrough is designed for high-frequency electrical signal transmission through vacuum chamber walls while maintaining a vacuum-tight seal. Featuring a single-pin configuration, 50-ohm matched impedance, floating shield, double-ended design, and a 1.285-inch diameter stainless steel weld adapter, this feedthrough provides an RF connection for laboratory, research, and industrial vacuum applications.

The Subminiature Type-A (SMA) connector design provides a compact solution for medium- to high-frequency applications. This matched impedance version is engineered for improved RF signal transmission at frequencies up to 8 GHz and incorporates a Teflon dielectric spacer to optimize electrical performance. The floating shield configuration provides electrical isolation between the coaxial shield and the mounting adapter. The double-ended design allows compatible SMA connections on both sides of the vacuum chamber wall.

Operating Conditions:

Electrical ratings are based on operation with one side in a dry atmosphere and the other side under vacuum at a maximum pressure of 1 x 10^-4 Torr. The matched impedance design incorporates a Teflon dielectric spacer for improved high-frequency performance, which may limit suitability for certain ultra-high vacuum environments and elevated-temperature applications. Temperature limitations associated with the mounting configuration may further restrict the operating range. Exceeding the maximum thermal gradient of 25°C per minute may damage the assembly.

Note: Verify SMA connector compatibility, RF frequency requirements, electrical ratings, and weld adapter dimensions before installation. Voltage and current ratings are based on the applicable SMA series specifications and should be confirmed for this matched impedance configuration.
