Description
SMA Jack (Female) Thread-In Straight Hermetically Sealed Connector | Stub Terminal | Stainless Steel Body
The PCA2FA50-HS1346A/9Q is a 50 Ohm SMA jack (female) thread-in straight hermetically sealed connector designed for high-frequency RF and microwave applications. Featuring a solder attachment with a stub terminal, this connector operates from DC to 26.5 GHz and provides a secure hermetic interface for systems that require signal integrity and environmental protection. Its SMA interface and thread-in design make it suitable for demanding aerospace, communication, testing, and instrumentation applications.Engineered for reliable RF performance, the connector supports frequencies up to 26.5 GHz with a VSWR of ≤1.25 and low insertion loss. The 50 Ω impedance design helps maintain stable signal transmission across broad operating frequencies.
The center contact is made from beryllium copper with gold plating, while the body is constructed from stainless steel with gold plating over a non-magnetic nickel-phosphorus underplating. PTFE insulation, a stainless steel metal gasket, and a glass seal contribute to hermetic protection. The connector supports at least 500 mating cycles and offers a helium leak rate not exceeding 1×10^-7 cc/sec.
Typical applications include hermetically sealed RF assemblies, aerospace electronics, microwave test systems, defense equipment, instrumentation, and high-reliability communication systems.
