1. Snap-on coupling mechanism makes it easy to
engage and disengage.
The rugged snap-on interface which uses no slotting in the outer
conductor maintains mechanical stability by allowing constant
mating force and rotation without degradation of electrical
performance.

2. Low Profile accommodates PCMCIA type cards
The MMCX-LR-SMT with a height of only 3.51mm can be mounted
on the bottom of the type 2 card. For installation on the PCB

5. Matched Excellent Impedance
The interface is slotless to minimize RF leakage. High frequency
characteristics achieve a maximum voltage standing-wave ratio
(VSWR) of 1.2 at DC-6GHz (typical value, that is not applicable to
all products).
6. Compatibility
Mates will all industry standard MMCX connectors.
