Ultra Miniature Snap-on Coaxial Connector (PC Card Type

2

Mountable)

MMCX Series

Right-angle Receptacle

Right-angle Receptacle + Straight Plug

■Features

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.

Right-angle Receptacle + Right-angle Plug

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

3. Designed for ultra thin cable

Industry Standard RG-type coaxial cable

··· RG-178B/U (Ø1.8)

··· RG-316/U (Ø2.59 max.)

Ø1.48

single shielded cable (one of the smallest available)

··· DFSS111-U1979 (Ø1.48) made by Junkosha Inc.

··· CO-6F·FH-SB (Ø1.48) made by Hitachi Cable Ltd.

··· RF-MF507 (Ø1.48) made by Nissei Electric Co., Ltd.

Vertical Receptacle + Straight Plug

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).

6. Compatibility

Mates will all industry standard MMCX connectors.
