2.4 mm RF Coaxial Connectors — Precision Connectivity for 50 GHz Microwave and mmWave Systems

Bridging the Gap Between Microwave and Millimeter Wave

   In the fast-evolving field of high-frequency engineering, the 2.4 mm RF coaxial connector represents a vital bridge between conventional microwave and emerging millimeter-wave technologies.
Engineered for operation up to 50 GHz, this connector series combines mechanical strength, precision alignment, and electrical stability—qualities essential for modern test systems, 5G mmWave modules, and aerospace communications.

   Where SMA connectors stop and 1.85 mm begins, the 2.4 mm family provides the perfect midpoint—offering both compatibility and performance that engineers trust for repeatable, low-loss connections.

Designed for Precision, Built for Reliability

   Every 2.4 mm connector is a study in controlled geometry.
   Its air-dielectric structure maintains a true 50 Ω impedance, while the thicker outer conductor prevents the thread deformation that can occur in smaller interfaces.

     Key specifications include:

     Frequency Range: DC to 50 GHz

     Impedance: 50 Ω

     VSWR: ≤ 1.15:1 typical

     Coupling: Threaded interface for torque repeatability

     Materials: Stainless-steel body with gold-plated beryllium-copper contacts

     Dielectric: Air for low loss and high stability

     Temperature Range: –55 °C to +165 °C

     Compliance: RoHS and REACH certified

   This robust architecture allows the 2.4 mm RF connector to maintain exceptional return loss and insertion loss characteristics even after thousands of mating cycles.

Precision Where It Matters

   At frequencies up to 50 GHz, even microscopic misalignment can create phase distortion or signal reflection. That’s why the 2.4 mm connector’s internal dimensions are machined with sub-micron tolerances, ensuring tight center conductor alignment and consistent phase repeatability.

   Engineers rely on these connectors in vector network analyzers (VNA), signal generators, and microwave test fixtures—applications where calibration integrity defines the accuracy of every measurement.

   With its low VSWR and rugged threaded coupling, the 2.4 mm series also performs flawlessly in high-density 5G mmWave systems, where every connection must support both high power and low reflection simultaneously.

Real-World Applications

   5G and 6G mmWave Development: Reliable interconnects for base-station and device testing

   Radar and Defense Electronics: Low-loss connectors for high-frequency modules and sensor arrays

   Aerospace Communication Systems: Stable performance under vibration and temperature extremes

   Microwave Test Equipment: Precision interfaces for calibration and signal integrity

   Research Labs and Universities: Standardized connectors for experiments beyond 40 GHz

   Wherever accuracy and frequency converge, 2.4 mm connectors ensure the connection remains as precise as the signal itself.

Compatibility and System Integration

   The 2.4 mm RF connector is mechanically compatible with 2.92 mm (K) and 3.5 mm connectors, making it an ideal upgrade for systems migrating from microwave to mmWave bands.

   Its threaded interface ensures secure, repeatable coupling torque—critical in test environments where connectors are engaged hundreds of times per week. This versatility allows seamless integration across measurement platforms, RF modules, and communication subsystems, reducing transition loss and connector complexity.
