For semi-rigid cables Receptacles connectors
SMB connectors feature quick connect/disconnect snap-on mating and are available in both 50 and 75ohm impedance structures. For maximum space utilization, we also offer a high 75ohm version. Using highly efficient die cast molds and high-speed fully automated assembly equipment, this series of connectors conforms to MIL-C-39012 and the interface is in compliance with MIL-STD-348. SMB connector line offers a cost effective solution for digital cellular PCN, Global Positioning System (GPS) and wireless LAN system.

Application:
Antenna, Base Station, Instrumentation, Microwave Component, PC/LAN, Process Control, Radio Board, Surge, Telecommunication, Test and Measurement, Video System, Wireless
