Ultra Miniature Snap-on Coaxial Connector (PC Card Type 2

Mountable)

sFeatures

1. Snap-on coupling mechanism makes it easy to

engage and disengage.

The rugged snap-on interface which uses no slotting in the outerconductor maintains mechanical stability by allowing constantmating force and rotation without degradation of electricalperformance.

2. Low Profile accommodates PCMCIA type 2cards

The MMCX-LR-SMT with a height of only 3.51mm can be mounted

on the bottom of the type 2card. For installation on the PCBsurface, the connector has a 0.36mm offset from the card centerline,which allows the card center axis to coincide with the connectorcenter axis.

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.

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), TNCand H.FL series.

5. Matched Excellent Impedance

The interface is slotless to minimize RF leakage. High frequencycharacteristics achieve a maximum voltage standing-wave ratio

(VSWR) of 1.2 at DC-6GHz (typical value, that is not applicable toall products).

6. Compatibility

Mates will all industry standard MMCX connectors.

sProduct Specifications

*Voltage standing wave ratio (V.S.W.R.) measuring system.

The above voltage standing wave ratio (V.S.W.R.) standard value is measured in the measuring system as shown below.

NOTE 1:The cable connector is measured with double ended 15cm cable

assembly.

NOTE 2:The PCB connector is mounted on the 50 ohms printed circuit

board, to which Hirose's adaptor is connected.
