QMA Connectors for Times Microwave LMR-400 Cable

Amphenol RF QMA Connectors for LMR-400

QMA 50 Ohm connectors offer consistent performance up to 6 GHz and feature snap-on coupling for quick and easy installation.

The QMA connector is a quick disconnect version of the SMA connector and shares the same internal construction, which allows the connector to have excellent performance up to 6 GHz. Because of the innovative coupling mechanism, a 360-degree butt joint is maintained resulting in low RF leakage. Since the RF line is identical to the SMA series, the QMA connectors also offer the same high power handling capability. This gives the series significant advantages over other quick disconnect connectors.

Mechanically, the QMA series offers a more convenient installation than SMA connectors. Because the interface mates with a snap-on instead of a threaded coupling, there is a significant time advantage. Typically, these connectors can be installed into a system 10 times faster than an SMA connector. Another benefit of eliminating the threaded coupling is the denser packaging. The pitch between connector can be reduced because there is no requirement for wrench clearance. Connectors can be rotated 360 degrees after they are mated which greatly improves the flexibility of installations.
