Field notes for buyers writing an RF requirement. These pages explain fields and evidence requests. They are not factory announcements.
Use a note when the drawing is still open. An SMP shroud and a threaded N body should not share one sentence. Record impedance, often a 50 ohm question, the frequency range, and whether VSWR or return loss is the limit you will compare. Public SMP outlines sometimes discuss a window that can reach 40 GHz. Type N outlines sometimes discuss about 11 GHz, with precision parts discussed toward 18 GHz. Those figures are prompts for the datasheet of the model a supplier names. They are not ratings assigned by this desk.
Plating such as 1.27 μm gold over nickel belongs with the underplate. Connector mating cycle counts belong with an IEC 60512 sequence. Ingress protection belongs to the sealed stack on the drawing. A named-interface body and a compatible body stay a buyer choice after pin, detent or thread, and plating are compared. Unused and refurbished shells stay a second choice after wear and lot records are shown. MIL-STD-348 can be a dimension question. FCC equipment authorization under 47 CFR Part 2 Subpart J stays with the radio when the part is passive. The desk does not certify a series, does not hold stock, and does not print a saving rate.
A seven-step sourcing checklist for B2B buyers of SMP, coaxial, and N-type RF connectors — built from five documented mistakes, not a marketing brochure. Covers custom RF connector manufacturing and how to verify US-based suppliers before you commit volume.
