QMA Male Straight Low PIM Coaxial Connector

QMA Connectors KTX QMA-KHD9

The QMA RF connector stands out as a versatile, high-performance solution for RF applications demanding quick, reliable, and tool-less connections. Its snap-on 360-degree rotating mechanism offers a significant advantage over traditional SMA connectors, reducing installation time without compromising electrical performance up to 18 GHz.

QMA vs. SMA Connectors: What’s the Difference?

While both QMA and SMA connectors share similar internal designs and electrical characteristics, their coupling mechanisms set them apart:

Feature	QMA Connector	SMA Connector
Coupling Mechanism	Snap-on, 360° rotating locking	Threaded coupling
Installation Speed	Quick, tool-less	Slower, requires screwing
RF Leakage	Very low (-120 dB max for DC-3 GHz)	Low, but slightly higher than QMA
Power Handling	Up to 75 W @ 10 GHz	Comparable
Mechanical Durability	Moderate, less robust under heavy vibration	High, suitable for harsh environments
Flexibility	Connectors can rotate after mating	Connectors can rotate after mating

The snap-on feature of the QMA connector significantly reduces assembly time and simplifies field servicing, making it a preferred choice in applications requiring frequent connect/disconnect cycles.
