Description
The 2.4mm interface was developed specifically to eliminate the “moding” issues found in SMA and 2.92mm connectors at higher frequencies. This adapter utilizes an air dielectric and a thickened outer wall to provide superior mechanical stability and a mode-free signal path up to 50 GHz. While it is mechanically compatible with 1.85mm (V-type) connectors, it is not compatible with SMA, 3.5mm, or 2.92mm without a dedicated inter-series adapter.
Most professional-grade 2.4mm adapters are manufactured from passivated stainless steel with gold-plated beryllium copper center contacts for maximum conductivity and a high mating cycle life. They are frequently used as port savers on expensive test equipment like Vector Network Analyzers (VNAs) to prevent wear on the internal ports.
Key Technical Advantages
-
Millimeter-Wave Range: Optimized for consistent, mode-free performance from DC up to 50 GHz.
-
Superior Durability: Stainless steel construction ensures long-term reliability and resistance to mechanical wear over 500+ mating cycles.
-
Precision Air Dielectric: Minimizes signal reflections, resulting in a VSWR typically ≤ 1.20:1 through the full frequency band.
-
Low Insertion Loss: High-grade plating and machining minimize signal attenuation (typically ≤ 0.3 dB).
-
Thermal Stability: Engineered to maintain electrical performance across a wide temperature range, typically -55°C to +165°C.
