Product details
The 142221-75 from Amphenol RF sets new benchmarks in Coaxial Connectors (RF) performance for satellite payload systems. Designed for GEO orbit conditions, this connector maintains flawless signal integrity through 15+ years of continuous operation in the space environment.Featuring SMB, Mini configuration, the connector achieves <0.001dB/mate insertion loss variation after 500 thermal cycles. The radiation-hardened dielectric prevents total dose effects up to 100kRad.With Plug, Female Socket architecture, the connector exhibits <1pA leakage current in vacuum. The molecular barrier coating prevents outgassing contamination of sensitive optics.Solder technology ensures stable contact resistance despite atomic oxygen exposure. The gold-iridium alloy contacts withstand >10,000 thermal cycles in LEO conditions.The Crimp system provides >100dB EMI shielding against solar flare events. The multi-foil design meets MIL-STD-188-164 requirements for spacecraft bonding.Precision-controlled 75Ohm maintains <0.5% deviation across -150 C to +125 C. The compensated dielectric design accounts for thermal expansion in vacuum.Designed for Free Hanging (In-Line), Right Angle installation, the connector withstands 50G vibration during launch. The titanium housing provides >98% radiation shielding effectiveness.Qualified with AT&T 735A space-grade cables, the connector passes NASA outgassing tests with <0.1% TML. The strain relief system survives 1,000 flex cycles in thermal vacuum.The Snap-On mechanism provides positive engagement with <5N m torque in zero-G. The captive hardware meets NASA-STD-8739.4 requirements.With 1 isolated channels, the connector supports redundant spacecraft systems. Each port features individual radiation-hardened ESD protection.The Gold anodization provides <5% solar absorptance in AM0 conditions. The optical properties remain stable under UV and proton radiation.The Beryllium Copper formulation resists cold welding in vacuum with <10mg contact force. The beryllium-copper alloy maintains spring properties at cryogenic temperatures.
