Product details
The A-4JA 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 AMC4 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 Jack, Male Pin 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 Solder system provides >100dB EMI shielding against solar flare events. The multi-foil design meets MIL-STD-188-164 requirements for spacecraft bonding.Precision-controlled 50Ohm maintains <0.5% deviation across -150 C to +125 C. The compensated dielectric design accounts for thermal expansion in vacuum.Designed for Surface Mount installation, the connector withstands 50G vibration during launch. The titanium housing provides >98% radiation shielding effectiveness.The Snap-On mechanism provides positive engagement with <5N m torque in zero-G. The captive hardware meets NASA-STD-8739.4 requirements.Characterized at 6 GHz, the connector shows <0.05dB PIM in high-power RF applications. The multipaction-resistant design handles 5kW peak power at altitude.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 Copper Alloy formulation resists cold welding in vacuum with <10mg contact force. The beryllium-copper alloy maintains spring properties at cryogenic temperatures.
