High-performance BMA-type RF coaxial connectors with blind-mate slide-on design. Ideal for 18GHz microwave, radar, 5G, and aerospace applications requiring compact, reliable RF interconnects.
Designed for Seamless RF Integration
In every complex RF system, the physical connection is as critical as the signal itself.
BMA-type RF coaxial connectors were created to solve one of the most challenging design problems — how to achieve high-frequency performance with blind-mate convenience in modular microwave assemblies.
Known as the “Slide-On SMA,” the BMA connector combines compact design with precise electrical control, supporting frequencies up to 18 GHz.
It allows quick engagement between modules or panels without threading, reducing installation time and mechanical stress while preserving signal integrity.
Bridging Design Flexibility and High-Frequency Stability
In aerospace, defense, and telecommunication infrastructure, system density is increasing while mechanical tolerances shrink.
The BMA connector series provides the ideal solution for high-density, high-frequency RF interconnects.
Its blind-mate coupling allows easy connection in environments where alignment is difficult — such as rack-mounted RF modules, antenna arrays, and microwave subsystems.
With a 50 Ω impedance and low VSWR, it ensures smooth signal transition and stable return loss even under vibration and temperature variation.
Engineers often use BMA connectors in satellite communication modules, 5G RF systems, and test and measurement equipment, where reliable blind-mate connections simplify design and improve maintainability.
Inside the Connector — Engineering Excellence
Every BMA RF coaxial connector is a combination of mechanical precision and electrical balance.
The spring-loaded outer conductor design compensates for axial misalignment, while the gold-plated beryllium copper contacts guarantee consistent conductivity and long service life.
The slide-on interface eliminates torque requirements, reducing mechanical wear and allowing quick replacement or reconfiguration of RF boards.
Each connector is tested for insertion loss, VSWR, and durability, ensuring it performs reliably through thousands of mating cycles.
Material options include stainless steel, brass with gold plating, and PTFE insulation, ensuring stability across temperature extremes from –65°C to +165°C.
Real-World Applications
The BMA-type RF coaxial connector is used wherever compactness, precision, and modularity meet:
Aerospace RF systems: for high-frequency interconnects in radar and satellite payloads
5G base stations: to simplify high-density antenna module integration
Microwave communication racks: enabling quick maintenance and module swaps
Test & measurement instruments: ensuring stable RF performance up to 18 GHz
Defense and radar systems: providing shock and vibration resistance with blind-mate ease
These connectors deliver low insertion loss, excellent return loss, and reliable mechanical retention, making them indispensable in next-generation RF architectures.
The Modern Approach to Modular RF
The demand for high-frequency modular systems is reshaping how engineers think about connectors.
The BMA connector series helps designers move away from rigid, threaded interfaces toward flexible, maintenance-friendly architectures.
By combining high-frequency stability with blind-mate functionality, BMA connectors reduce downtime during assembly and testing.
Their compatibility with SMA and SMP families also simplifies integration into existing RF systems, allowing easy upgrades without redesign.
This connector family is not just a mechanical link — it’s a system enabler, allowing compact RF module interconnects in applications where reliability cannot be compromised.
