QMA Quick Disconnect Connectors

Amphenol RF QMA Quick Disconnect Connectors offer snap-on mating in a denser package (12.4mm pitch) because wrench clearance is not needed. This quick-disconnect version also substantially decreases installation time. Using the same RF line as an SMA allows for excellent performance up to 6GHz. Amphenol RF QMA connectors offer a coupling mechanism in which a rotatable 360° butt joint is maintained, resulting in low RF leakage. The connectors can be rotated 360° after they are mated to improve the flexibility of installations. The QMA series is Quick Lock Formula (QLF) compatible, allowing for intermateability between manufacturers.
