sFeatures
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
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
surface, the connector has a 0.36mm offset from the card centerline,
which allows the card center axis to coincide with the connector
center axis.

4. Cable Assemblies with multiple design options
By using
Ø1.48
single shielded cable, the opposite end of the
assembly can be connected with N, BNC, HRM (SMA type), TNC
and H.FL series.
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).
