Reverse Polarity SMA (RP-SMA) Jack-Female to MMCX Adapter

AIR802® part number AD-RSJMMCX is a 50 ohm coaxial adapter from a reverse polarity SMA (RP-SMA) jack-plug to a MMCX plug-male connector type.

This adapter, part number AD-RSJMMCX is a reverse polarity SMA (RP-SMA) jack or female to MMCX plug or male coaxial connector adapter. MMCX connectors provide a lock-snap connecting mechanism and allows 360 degree rotation in the mating connector. MMCX connectors are commonly found in 802.11b/g/n Wi-Fi radio printed circuit boards.

AIR802® manufactures high precision and performance adapters and connectors. Adapter and connector selection is extremely important to insure proper operation and reliability. Poorly constructed adapters and/or connectors will cause higher VSWR and insertion loss resulting in electrical noise and intermittent issues. AIR802® manufactures very large quantities of adapters and connectors for our global customers allowing us to provide an attractive quality to price ratio.

In choosing adapters and/or connectors, it is important to match one to the type of cable being used, the impedance (50 versus 75 ohms), the frequency support, insertion loss, voltage rating and environmental specifications. Adapters are very useful for matching different connector types.

Note that there are both SMA and reverse polarity SMA (RP-SMA) connector types. The SMA jack / female does not have a pin protruding. However the RP-SMA jack / female does have a pin protruding. We point this out in order to minimize confusion for those not familiar with the various connector types.
