3.5mm Female to N Female RF Adapter

The 3.5mm Female to N Female RF Adapter – 3.5/N-KK1, also referred to as N Female to 3.5mm Female RF Adapter – N/3.5-KK1, is a precision-engineered coaxial adapter designed for stable, low-loss signal transitions between 3.5mm and N-type interfaces. This straight adapter facilitates high-frequency testing with durable N-type components often used in ruggedized RF environments.

Rated up to 18 GHz and maintaining a 50-ohm impedance, the 3.5mm Female to N Female RF Adapter supports seamless integration between high-precision lab instruments and field-deployable RF systems. This 3.5mm between-series adapter is widely used in applications such as end-of-line quality verification, radar and EW subsystems, and controlled lab testing.

With excellent electrical performance—VSWR ≤1.09 and insertion loss ≤0.2 dB—this 3.5mm straight adapter ensures consistent signal fidelity across its full frequency range. The 3.5mm Female to N Female RF Adapter is especially suited for engineers working with mixed-interface systems that require minimal mismatch and maximum durability.

Constructed with a passivated stainless steel body and gold-plated beryllium copper contacts, the 3.5/N-KK1 female to female adapter provides robust mechanical strength and long-term electrical stability. Its operational temperature range of -55°C to +165°C allows for reliable use in both lab and outdoor field deployments.

RoHS and REACH compliant, the 3.5mm Female to N Female RF Adapter is ideal for bridging high-performance test equipment with rugged RF infrastructure. Customized versions of this 3.5mm female adapter can be developed upon request to accommodate specific mechanical or electrical constraints in aerospace, telecom, or defense applications.
