2.4 mm RF Connectors Guide: Types, and Structure
What are 2.4 mm RF Connectors?
The 2.4 mm RF connector is a high-performance miniature connector designed for frequencies up to 50 GHz. It features a 50 Ω impedance and a precision threaded coupling mechanism for stable and repeatable connections.
It is mechanically compatible with 1.85 mm (V-type) connectors, but not compatible with 2.92 mm (K-type), 3.5 mm, or SMA connectors.
2.4 mm RF Connector Compatibility with 1.85 mm V Connectors
2.4 mm RF connectors are mechanically compatible only with 1.85 mm (V-type) connectors,
and not with 2.92 mm (K), 3.5 mm, or SMA connectors.
They use an air-dielectric design and precise thread coupling to maintain stable performance
up to 50 GHz.
Because of tighter mechanical tolerances, inter-mating with incompatible connector types
can lead to damage or measurement errors.
Adapters between 2.4 mm and other connector series are available for safe conversion when needed.
Improper mating may result in permanent damage to the connector interface.

2.4 mm RF Connector Features
High-Frequency Performance
2.4 mm RF connectors are designed for stable operation up to 50 GHz, making them suitable for high-frequency testing and measurement applications.
They feature an air-dielectric structure, which reduces dielectric loss compared to traditional PTFE-based designs, enabling improved signal integrity at higher frequencies.
The larger outer conductor compared to SMA-type connectors helps improve impedance stability and reduce signal loss at higher frequencies.
Compatibility with 1.85 mm (V) Connectors
2.4 mm connectors are mechanically compatible with 1.85 mm (V-type) connectors, allowing flexible use in mixed high-frequency test systems.
However, due to tight mechanical tolerances, improper mating or repeated use with different connector types may lead to wear or damage.
They are not compatible with SMA, 3.5 mm, or 2.92 mm (K-type) connectors.
