The SIPU RF Technology N Male to SMA Female Adapter (model SIPU-N/SMA-JK) is designed for inter-series connections in a harsh RF environment. This precision adapter mates ruggedised N-type interfaces to compact SMA systems. Operating from DC-11GHz with a VSWR of ≤1.3 and insertion loss of just ≤0.06√F(GHz)dB.
This is a military grade standard adapter with 50Ω characteristic impedance from the source to the antenna. Center conductor is beryllium bronze, gold plated and outside conductor is brass, nickel plated for improved conductivity. Your RF systems get dependable performance in tough conditions with 500 mating cycles and operating temperature range from -65℃ to +125℃.

The N Male to SMA Female Adapter solves inter-series incompatibility challenges in complex RF installations. You get consistent 50-ohm transitions without signal degradation. The low insertion loss design preserves your signal quality across the entire frequency spectrum.
Every adapter undergoes rigorous quality control. We test plating thickness and layer bonding strength for each production batch. RoHS environmental compliance ensures you meet international standards. The dielectric withstanding voltage testing guarantees 1,000V tolerance, providing peace of mind in high-voltage scenarios.
This straight-orientation adapter connects your heavy-duty N-type outdoor equipment to precision SMA-based indoor instruments. The compact design fits tight spaces while maintaining mechanical stability. PTFE dielectric material delivers consistent performance across temperature extremes.
Connect N-type base station antennas to SMA-equipped 5G wireless gateways. The adapter withstands outdoor moisture and temperature fluctuations. Your cellular networks maintain reliable connections in challenging tower environments.
Interface your high-power RF cables with SMA ports on Vector Network Analyzers and Spectrum Analyzers. Achieve accurate calibration without compromising measurement precision. The gold-plated center contact ensures stable readings during extended testing sessions.
Bridge ruggedized N-type bulkhead connectors to compact SMA modules in aerospace applications. The 500-cycle durability rating supports frequent reconfigurations. Your test benches benefit from flexible connectivity without investing in multiple cable assemblies.

SIPU RF Technology does extensive quality checking at every production step. Each N Male to SMA Female Adapter undergoes insulation and dielectric withstanding voltage testing using specialised equipment. We check the quality of the coating by measuring the thickness and by performing adhesion tests per batch.

Our production processes are ISO 9001 certified. We provide CE and RoHS certified solutions supported by 25+ years of RF technical knowledge. The beryllium bronze center conductor keeps the contact resistance low throughout the service life of the adapter.

The straight form makes it easier to mount both horizontally and vertically. First, tighten the N-type threaded connection by hand, then secure the SMA interface. Don’t crank on it too hard – you want to keep that 500 cycle rating.
Periodically inspect contact surfaces in high-vibration settings. Clean contacts with isopropyl alcohol as needed. Keep unused adapters under protective caps to avoid infection. The silicone rubber seal prevents moisture from entering when used outdoors.
Q: What frequency range does this adapter support?
A: The adapter operates from DC to 11GHz with maintained performance specifications throughout the range.
Q: Can I use this adapter in outdoor installations?
A: Yes, the operating temperature range of -65℃ to +125℃ and silicon rubber sealing make it suitable for outdoor use.
Q: How many times can I connect and disconnect the adapter?
A: The adapter is rated for 500 mating cycles under normal operating conditions.
