• BERYLLIUM COPPER CENTER CONTACT — MAINTAINS SPRING FORCE AFTER THOUSANDS OF MATING CYCLES: Standard brass center contacts lose spring tension after repeated insertions — contact force drops, increasing contact resistance and introducing measurement uncertainty. Beryllium copper (BeCu) has three times the elastic modulus of brass, maintaining consistent contact force and low contact resistance through thousands of mating cycles without permanent deformation. The same center contact material used in Keysight, Anritsu, and Rohde & Schwarz precision adapter series — now available at a fraction of OEM adapter cost.
• PRECISION DC TO 18GHz — VNA PORT SAVER FOR N-TYPE INSTRUMENT PORTS: N-type test ports on VNAs, signal generators, and spectrum analyzers are expensive to replace when threads strip or contact surfaces wear. Installing this SMA Female to N Male adapter as a port saver absorbs all mating cycles on the adapter — not on the instrument's native port. The adapter's DC to 18GHz rated performance and ≤1.20:1 VSWR ensure it does not limit measurement bandwidth or introduce reflection errors in S-parameter characterization up to 18GHz.
• SMA FEMALE TO N MALE — CORRECT GENDER FOR INSTRUMENT PORT TO CABLE CONNECTIONS: Side A: SMA Female (center hole, internal threads) — accepts SMA Male plugs on test cables, calibration standards, and SMA-port accessories. Side B: N Male (center pin, external threads) — plugs into N Female ports on VNA test ports, spectrum analyzer inputs, signal generator outputs, and N-type calibration kits. This Female-to-Male configuration is the standard for connecting SMA test accessories to N-type instrument ports without additional adapters. Impedance 50 Ohm, PTFE dielectric insulation.
• SUS303 PASSIVATED STAINLESS STEEL — DIMENSIONAL STABILITY THROUGH HEAVY LAB USE: Machined from passivated SUS303 stainless steel — significantly harder than brass — maintaining precise interface dimensions at both the SMA and N-type mating surfaces through rigorous daily lab use. Stainless steel resists the thread galling and interface deformation that occurs on brass adapters when overtorqued or mated at slight angular misalignment. Passivation treatment provides additional corrosion resistance. Temperature range -55°C to +165°C, RoHS compliant.
• COMPATIBLE WITH PRECISION VNA AND MICROWAVE TEST EQUIPMENT — DC TO 18GHz: Interface dimensions conform to IEC 61169-1 (SMA) and IEC 61169-16 (N-type) precision connector standards. Compatible with: Keysight ENA/PNA series VNA N-type ports, Anritsu MS46122B/MS2090A N-type ports, Rohde & Schwarz ZNL/ZVA N-type test ports, Copper Mountain Technologies S5243 VNA, and any precision RF instrument with N Female test ports requiring SMA Male accessory connection. Also suitable for connecting SMA-terminated calibration standards to N-type VNA ports during SOLT calibration procedures.
