SMPM Plug for 0.047" Semi-Rigid, DC to 35 GHz
It belongs to the 92512 series of precision RF connectors, designed for the 0.047" semi-rigid cable group. The body is machined from beryllium copper with a gold finish — the same gold-over-beryllium copper construction carries through the center contact. Snap-on fastening gives a positive lock without threads, which saves space in dense panel or module layouts.
35 GHz Bandwidth and 50 Ohm Impedance
Rated to 35 GHz, this SMPM plug handles Ku-band, K-band, and into the lower Ka-band without a mode change. The 50 Ohm impedance is a standard match for most RF test cables, microwave modules, and antenna feeds. For a cable assembly shop, the 35 GHz ceiling means this connector works on any signal up to that frequency — you don't need a different part for X-band versus K-band runs.
Both the shield and the center contact terminate by solder — no crimp tooling required. The connector is specified for 0.047" semi-rigid cable, which is the standard diameter for RG-402 and similar low-loss microwave coax. That means you get the full assembly kit in one order code — no separate sourcing for the contact or dielectric. Free-hanging (in-line) mounting lets you use it as a cable-end plug or a panel-mate with the right bulkhead jack.
Durability and Mating Cycles
The snap-on coupling mechanism is faster to engage than a threaded SMA — useful when you're swapping cables on a VNA or a test fixture multiple times per shift.
