The body and center contacts are machined from beryllium copper with gold plating on the signal path, giving the snap-on retention its repeatable cycle life and keeping passive intermodulation low across the band. ## What the 40 GHz rating means for the signal path 40 GHz is the top end of the SMP interface — this adapter doesn't roll off early. The straight body keeps the signal path clean with no right-angle bend to add a mode conversion or a standing-wave bump. In a test setup or a system interconnect running K-band or millimeter-wave, this barrel passes through the full band without introducing a VSWR discontinuity that would show up on a network analyzer sweep. The PTFE dielectric holds the impedance stable from DC through 40 GHz, which is the same dielectric used in high-performance semi-rigid cable assemblies. ## SMP-to-SMP gender changer — same-series, no interface mismatch This adapter converts SMP male to SMP male by providing two female SMP jacks back-to-back. Both ends are SMP, same series, so there is no interface transition — no SMP-to-SMA or SMP-to-2.92 mm step that would add a loss bump. The snap-on fastening on both ends locks the plug into the adapter with a positive detent; no coupling nut to torque, just push until it clicks. The free-hanging in-line body sits in the cable path without a panel flange or a bulkhead mount, so it works as a bullet between two cable-mounted plugs or between a cable plug and a board-mount jack. ## Materials and build — beryllium copper and gold across the RF path The body and the center contacts are both beryllium copper, a spring alloy that holds its shape through repeated snap-on engagements. Gold plating on the center contact and on the body finish keeps the mating surfaces corrosion-free and maintains a stable contact resistance over the life of the interconnect. The BeCu spring fingers in the female jack are what give the SMP interface its rated mating cycle count — the material doesn't take a set after the first few mates.","metaTitle":"Molex 0734066416 SMP Jack-to-Jack Adapter, 50 Ohm, 40 GHz","metaDescription":"Molex 0734066416 SMP female-to-female adapter, straight in-line, 50 Ohm impedance, rated to 40 GHz.
