MMCX Receptacle for RF Interconnects
The TE Connectivity 1-1634010-0 is a Greenpar series MMCX receptacle with a female socket interface, designed for 50 Ohm impedance RF signal paths. This right-angle, through-hole mounted connector uses a snap-on fastening mechanism and carries a 6 GHz maximum frequency rating, making it suited for compact RF modules, test equipment, and wireless infrastructure where board-space is constrained and quick connect/disconnect is needed.
RF Performance and Signal Integrity
The 50 Ohm impedance and 6 GHz bandwidth define the usable frequency range — at 6 GHz the connector maintains a controlled impedance transition through the PTFE dielectric, which has stable dielectric properties across the full -55°C to 155°C range. The snap-on mating interface provides consistent axial force for repeatable RF performance across 500 mating cycles, though the gold-over-beryllium copper center contact is the wear surface that governs cycle life. For designs requiring phase stability or low VSWR, the right-angle launch geometry introduces a small impedance discontinuity at the board transition that should be accounted for in the microstrip or coplanar waveguide design.
No official successor order code is listed on record. Engineers specifying new designs should select a current-production MMCX receptacle from the Greenpar or equivalent series to avoid future supply gaps.
The snap-on mating interface accepts standard MMCX plugs; no special tooling is needed beyond the solder iron. The gold body finish provides corrosion resistance in indoor and controlled environments, though the connector is not sealed — avoid washdown or condensing humidity exposure.
