Information
MMCX RF Connectors
MMCX connector is one kind of RF connectors. This MMCX connector is jack/ female, 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 RG178 and RG196 RF coaxial cable. Its plating is Gold over brass and the impedance is 50 ohm.
MMCX connector is small size in RF connector. MMCX Connector belongs to snap-on mating. Besides, MMCX jack crimp series still have Right angle jack , straight bulkhead 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 connectors, or RF cables, please contact us.
MMCX connector jack straight crimp type can be terminated with RG178/ RG196 RF coaxial Cable to be RF Cable assembly and play the role to transmit RF Signal in telecommunications. MMCX RF connector is most commonly used in GPS Antenna, GSM Antenna or GPS/GSM application these kinds of RF connectors industry.

Cable Assembly
Cable Assembly Instructions Crimp type
Step1. All parts of MMCX connector 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, insulator, spacer onto cable conductor and then spread out the shielding.
Step4. Solder the cable inner conductor into the connector contact pin, and solder through the side hole to fix it.
Step5. Push the contact pin and other parts into the connector 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.
