MMCX Straight Crimp Plug for RG174,RG316

MMCX Straight Crimp Plug for RG174,RG316


MMCX connector is one kind of RF connectors. This MMCX connector is plug/ male and straight type. It’s designed to terminate with RF Coaxial Cable by crimping to be MMCX adaptor RF cable. The applicable RF coax cable is RG174/ RG316/ RG188/ LMR100 RF coaxial cable. It is gold plating and 50 ohm impendence.

MMCX connector is small size in RF connector. MMCX Connector’s mating is snap-on type. Besides, MMCX plug/ male crimp series have straight and right angle outlook. MMCX Connector commonly is used for 0~3GHz. If you need higher working frequency or any special request about RF connector & RF cable, just please free to contact us.

MMCX connector plug straight crimp type can be terminated with RG174/ RG316/ RG188/ LMR100 RF coaxial Cable to be RF Cable assembly and charge in transmitting RF Signal in telecommunications. MMCX RF connector is most commonly used in GPS/GSM Antenna (internal or external) or GPS/GSM application these kinds of RF connectors industries.

Cable Assembly

Cable assembly Instructions Crimp type

Step1. All parts of MMCX connector are shown as the top line.

Step2. Strip the RG174 into center conductor, insulator, shielding three parts per recommended stripping dimension shown in connector spec.

Step3. Slide the ferrule onto the cable jacket.

Step4. Put the center conductor into the contact pin of MMCX plug and then solder through the hole.

Step5. Put the contact pin into main body until it stops and then spread out the shielding onto the knurled part and then

Step6. Slide the ferrule over the shielding, and proceed the first open-short test to make sure signal can transmit well.

Step7. Crimp the ferrule to let it become tighter.

Step8. Wear the heat shrink onto the ferrule and then shrink it.

Step9. Do the open-short test of every cable assembly before QC examination.
