3.5mm Female to 2.4mm Male RF Adapter

The 3.5mm Female to 2.4mm Male RF Adapter – 3.5/2.4-KJ1, also referred to as 2.4mm Male to 3.5mm Female RF Adapter – 2.4/3.5-JK1, is a high-frequency coaxial adapter engineered for reliable, low-loss connections between 3.5mm female and 2.4mm male interfaces. This straight RF adapter provides a practical transition between general-purpose RF systems and precision-grade test equipment.

Rated up to 26.5 GHz with a 50-ohm impedance, the 3.5mm Female to 2.4mm Male RF Adapter is ideally suited for use in metrology environments, lab-grade test fixtures, and compact modular assemblies. This 3.5mm between-series adapter plays a key role in applications such as end-of-line quality verification, high-frequency 5G module testing, and controlled lab testing.

This 3.5mm to 2.4mm straight coaxial adapter maintains excellent RF performance with a VSWR ≤1.12 and insertion loss ≤0.25 dB, supporting accurate signal transmission with minimal reflection or degradation. It is a practical solution for connecting 2.4mm instrumentation with legacy or more durable 3.5mm assemblies.

Constructed from passivated stainless steel and featuring gold-plated beryllium copper contacts, the 3.5/2.4-KJ1 between-series adapter offers exceptional durability and long-term reliability in both field and lab conditions. This female to male 3.5mm adapter withstands operating temperatures from -55°C to +165°C, delivering stable performance even in challenging RF environments.

RoHS and REACH compliant, the 3.5mm Female to 2.4mm Male RF Adapter is the ideal solution for engineers working in telecom testing, aerospace RF systems, and next-generation wireless infrastructure. Customized versions of this adapter can be supplied upon request to meet specific connector arrangements or mechanical constraints.
