It presents a female socket on both ends, meaning it joins two SMP male plugs — a common need when extending a blind-mate interconnect or re-routing a test cable assembly. The gold finish on the body and center contact protects against corrosion and maintains low intermodulation in repeated mate cycles. Snap-on fastening on both ends matches the standard SMP blind-mate interface — no torque wrench, no coupling nut, just axial push to engage and a straight pull to disengage. The dielectric is PTFE, the standard for high-frequency coax up through Ka-band. With 100 mating cycles rated, this adapter is suited for test bench reconfiguration and field-replaceable module interfaces where the connector sees regular connect-disconnect duty, not a permanent solder-down install. ## What the 40 GHz and 50 Ohm Ratings Mean for Your RF Path The 40 GHz max frequency is the practical ceiling for this SMP interface geometry — above that, the air-gap tolerance and contact repeatability start to introduce mode conversion. At 40 GHz, the adapter's electrical length is a fraction of a wavelength, so its insertion loss is dominated by the contact resistance at the two SMP interfaces rather than the body itself. The female-to-female center gender is the key selection axis. If your signal path terminates in SMP male plugs on both ends — common on module RF ports and test cable assemblies — this adapter bridges them directly. An SMP male-to-male adapter (female center contacts on both ends) would serve the opposite case of joining two female jacks. The SMP-FS2A-2030 covers the male-to-male cable or module interconnect scenario.","metaTitle":"SMP-FS2A-2030 SMP Adapter, 50 Ohm, DC-40 GHz, Female-Female","metaDescription":"SMP-FS2A-2030 SMP plug-to-plug adapter, 50 Ohm impedance, DC to 40 GHz.
