In professional RF and microwave applications, the MMCX connector female has become the go-to choice for premium custom coaxial cables. But why are engineers increasingly specifying this compact connector over alternatives like SMB jack connectors? Let’s examine the technical advantages that make MMCX the preferred solution for demanding coaxial cable assemblies.
Technical Superiority of MMCX in Coaxial Cable Systems
Enhanced Signal Integrity for Precision Applications
Our MMCX female connector maintains excellent impedance matching (50Ω) across wide frequency ranges (DC-6GHz), minimizing signal loss in high-speed data transmission. This makes it perfect for:
- Test & measurement equipment
- 5G infrastructure
- Medical imaging systems
- Aerospace telemetry
Robust Mechanical Design for Industrial Use

Unlike standard RF connectors, our MMCX coaxial connectors feature:
- Gold-plated brass contacts for superior conductivity
- Stainless steel housing for EMI shielding
- 360° rotation capability to prevent cable damage
- 500+ mating cycle durability
MMCX vs. Alternative Coaxial Connectors
Space-Saving Advantage Over SMB

While SMB jack connectors offer good performance, our MMCX coaxial cable connectors provide:
- 40% smaller footprint
- Lighter weight (ideal for drone/UAV applications)
- Easier PCB mounting options
Customization Flexibility
We specialize in custom MMCX cable assemblies with:
- Various cable types (RG178, RG316, etc.)
- Multiple shielding options
- Custom lengths and configurations
- Strain relief solutions
