Information
MMCX connector is one series of RF connectors. This MMCX connector is jack/ female, and straight bulkhead type. This MMCX jack bulkhead type will be terminated with RF Coax Cable to be MMCX cable assembly for signal transmitting. The applicable RF coax cable is RG174/ RG316/ RG178/ LMR100/RD316/RG188 RF coaxial cable. Its plating is Gold over brass and the impedance is 50 ohm.
MMCX connector is kind of small in RF connector. MMCX Connectors have snap-on mechanical mating design. Besides, MMCX jack crimp series still have Right angle jack , straight crimp jack, PCB mount jack, edge mount jack and SMT jack. MMCX Connector commonly is used for 0~3GHz. If you need higher working frequency, special mechanical design, customized RF connector, or RF cables, please contact us.
MMCX connector jack straight bulkhead crimp type can be terminated with RG174/ RG316/ RG178/ LMR100/RD316/RG188/RG196 RF coaxial Cable to be RF Cable assembly. It can transmit RF Signal well in various telecommunications. MMCX RF connector is most commonly used in GPS internal Antenna, GSM external Antenna or GPS/GSM application these kinds of RF industry.

Cable Assembly
Cable assembly Instructions Crimp type
Step1. All parts of MMCX Straight Bulkhead Crimp Jack are shown as the top line.
Step2. Strip the cable into center conductor, insulator, shielding three parts per recommended stripping dimension shown in connector spec.
Step3. Slide the ferrule onto the cable jacket.
Step4. Solder the cable inner conductor into the connector contact pin.
Step5. Spread out the shielding and put the contact pin into main body until it stops and then cover the shielding onto the knurled part.
Step6. Proceed the first open-short test to make sure signal transmit well.
Step7. Slide the ferrule over the main body and crimp it 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.
