Ultra Miniature Snap-on Coaxial Connector (PC Card Type 2 Mountable)
MMCX Series
Right-angle Receptacle Right-angle Receptacle
Right-angle Receptacle + Straight Plug Right-angle Receptacle + Straight Plug
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. Low Profile accommodates PCMCIA type 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. Vertical Receptacle Vertical Receptacle
3. Designed for ultra thin cable
Industry Standard RG-type coaxial cable *** RG-178B/U (O1.8) *** RG-316/U (O2.59 max.) O1.48 single shielded cable (one of the smallest available) *** DFSS111-U1979 (O1.48) made by Junkosha Inc. *** CO-6F*FH-SB (O1.48) made by Hitachi Cable Ltd. *** RF-MF507 (O1.48) made by Nissei Electric Co., Ltd.
Vertical Receptacle + Straight Plug Vertical Receptacle + Straight Plug
4. Cable Assemblies with multiple design options
By using O1.48 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).
