The qma connectors interface has a very similar performance to theSMA,but in addition it offers an easier, faster and safercoupling operation,helping customers to save significantlytime during production. The packaging density of qma connectors isincreased compared to SMA connectors thanks to the fact thatno torque spanner is required to fasten the coupling nut.QMA is not intermateable with SMA.QMA connectors are also available as waterproof version(IP68) and are compatible with QLF standard.
QMA Connectorsare fast plug-in solutions designed for high frequency radio frequency (RF) applications, widely used in communications base stations, test equipment, industrial control and military electronics. Here are its core product features and advantages:
Product features of QMA Male Connector
Quick Lock Design:
The QMA Male Connector uses a push-pull self-locking structure that allows quick insertion and removal without rotation (70% faster than traditional threaded connections) and is suitable for frequent operation scenarios.
High frequency stability:
Support working frequency range of 0 ~ 6 GHz, impedance of 50ω, VSWR ≤1.25, ensure low loss and high reliability of signal transmission.
Durable Materials:
The shell is made of nickel-plated brass or stainless steel, and the internal contacts are gold-plated, anti-oxidation and corrosion-resistant, and the plug life can reach more than 500 times.
Advantages: simplify installation process, improve maintenance efficiency, suitable for 5G base station, vehicle communication and other dynamic environment.
2. QMA RF Connector Advantages
Compatibility and flexibility:
QMA RF Connector compatible with RG174, RG316 and other coaxial cable, provide Right-Angle (Right-Angle) and Straight head (Straight) interface form, adapt to the compact space layout.
High shielding effectiveness:
All-metal shielding structure effectively suppresses electromagnetic interference (EMI) and ensures Signal integrity, suitable for high-density electronic equipment.
