QMA Rf Coaxial Connector Instructions

QMA Cable Mount Connectors


QMA RF connectors offer the same high quality and performance as SMA RF connectors, which are "quick disconnect" version of SMA connectors. XAHonor provides 50 Ohm QMA cable mount connector , which is available for RG58, RG141, RG316, LMR195, LMR200, LMR240 cables. We utilize a crimp and solder attachment process for a strong and effective attachment.

XAHonor produces and sales QMA cable mount connectors in male or female gender, including straight plugs QMA cable connectors, straight Jacks QMA cable connectors, right angle plugs QMA cable connectors are available.

RA QMA connectors from Fairview Microwave are part of the very extensive selection of radio frequency interconnect components. Fairview RA QMA connectors include male genders in 50 Ohm impedance levels. Our right angle QMA connectors are available in standard polarity designs with mountless types.

The right angle QMA connector product line for coax are available with various crimp/non-solder contact and crimp/solder attachment methods. Fairview Microwave standard and other special configurations right angle QMA connectors are also in-stock for same day shipment. RA QMA connector compatible cable types include: LMR-240.

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.

QMA[1] and QN[2] connectors are the quick lock version of SMA and N connectors. This design can save much handling time because it allows quick mating and demating without tools. Due to the smaller overall size, it can save the operating space and allows for high density arrangement. To make cable routing easier, it can rotate 360 degrees after installation.

The Mini-QMA is a quick-locking SMA (QMA) replacement that was designed with panel mount and printed circuit board (PCB) applications specifically in mind; the length of the Mini-QMA being the shortest of any QMA connector on the market to date. This miniaturization, in addition to its snap-on coupling mechanism and electronic performance equivalent to SMA up to 18 GHz, make the Mini-QMA an excellent choice for applications in which space is limited but performance is required.
