• PRECISION DC TO 18GHz — EXTENDS YOUR VNA MEASUREMENT RANGE TO MICROWAVE FREQUENCIES: Standard brass adapters are rated to 6-12GHz. This stainless steel precision adapter maintains calibrated performance to 18GHz — covering the full operating range of most vector network analyzers (Keysight E5063A, Anritsu MS46122B, Rohde & Schwarz ZNL) and microwave signal generators. Ultra-low VSWR ≤1.20:1 across the full band ensures the adapter itself does not introduce reflection errors that corrupt S-parameter measurements or insertion loss characterization above 6GHz.
• STAINLESS STEEL SUS303 PASSIVATED BODY — WITHSTANDS RIGOROUS LAB MATING CYCLES: Soft brass adapter bodies deform at the connector interface after repeated high-torque mating cycles, particularly on VNA ports that are connected and disconnected dozens of times daily. This adapter is machined from passivated SUS303 stainless steel — significantly harder than brass — maintaining dimensional tolerance at the mating interface through thousands of cycles without thread galling or contact deformation. Passivation treatment provides additional corrosion resistance in humid laboratory environments.
• N FEMALE TO SMA FEMALE — CORRECT GENDER FOR CABLE-TO-INSTRUMENT CONNECTIONS: Side A: N Female (center hole, external threads) — accepts N Male plugs on feedline cables, power meters, and antenna connectors. Side B: SMA Female (center hole, internal threads) — accepts SMA Male plugs on VNA test port cables, signal generator outputs, and SMA-terminated test leads. This Female-to-Female configuration is the standard interconnect for joining an N-type cable plant to SMA-port instruments without additional adapters. Impedance 50 Ohm, temperature range -55°C to +165°C, RoHS compliant.
• PRECISION INTERFACE DIMENSIONS — COMPATIBLE WITH KEYSIGHT, ANRITSU, R&S, COPPER MOUNTAIN: Connector interface dimensions conform to IEC 61169-1 (SMA) and IEC 61169-16 (N-type) precision connector standards — the same dimensional specifications used by Keysight, Anritsu, Rohde & Schwarz, Copper Mountain Technologies, and Planar 804/1 VNA port connectors. Ensures repeatable mating force and consistent electrical contact at both interfaces across repeated calibration cycles. Suitable for use as a calibration reference adapter when the adapter's S-parameters have been characterized.
• WIDE RF APPLICATION — VNA CALIBRATION, ANTENNA TESTING, MICROWAVE LAB BENCH: N Female to SMA Female adapters are used wherever an N-type cable or component must connect to an SMA-port instrument: extending a VNA SMA test port to an N-type device under test; connecting an N-type calibration standard to an SMA VNA port; bridging an N-type power sensor to an SMA signal source; or adapting an N-type antenna feedline to an SMA spectrum analyzer input for site survey measurements above 6GHz. NOT for consumer WiFi or RP-SMA applications.
