Overview
SMA (SubMiniature version A) connectors and adapters are essential components in RF testing and high-frequency applications. Engineered for reliability and high performance, our precision SMA family supports a wide frequency range and is available in both stainless steel and gold-plated copper versions. These components are ideal for test environments demanding both durability and signal integrity.
Key Features
-
Compact Design: Miniature form factor ideal for space-constrained applications
-
Wide Frequency Range: Supports up to 18 GHz and 27 GHz depending on the model
-
Outstanding Electrical Performance: Ensures signal accuracy and stability
-
High Reliability: Built to withstand rigorous testing environments and long-term use
Performance Testing
Every connector and adapter undergoes 100% testing, with detailed test plots available upon request. Example results include:
-
3.8 GHz: VSWR as low as 1.01
-
18 GHz: VSWR around 1.10
-
26.5 GHz: VSWR maintained at 1.20
These values reflect the superior impedance matching and minimal signal reflection of our products.
Applications
Our SMA connectors and cable assemblies are widely adopted in:
-
Microwave Communication Systems
-
Aerospace and Navigation Equipment
-
Defense and Weapon Systems
-
Precision RF and Microwave Test Instruments
Conclusion
For industries requiring precise, high-frequency signal transmission, our SMA connector and adapter family offers the performance and reliability needed. Whether you choose stainless steel or gold-plated copper, these components ensure consistent results in the most demanding environments.

With options like SMA, N-Type, and 2.92mm available, picking the right one feels complex and mistakes can be costly. SMA is common up to 18 GHz, N-Type is larger and robust for power/outdoor use up to 11-18 GHz, while 2.92mm offers precision performance up to 40 GHz and is mechanically compatible with SMA. Selecting the
Introduction to VSWR Voltage Standing Wave Ratio (VSWR) is a critical parameter in RF (Radio Frequency) systems, indicating how effectively power is transferred from a source to a load. It measures the ratio of the maximum to the minimum voltage in a standing wave formed by reflected and transmitted signals.
If you are a newcomer in the RF industry, it must be difficult to distinguish VSWR and return loss. The following is a comparison table of VSWR and return loss.
SMA Connectors/Adapters and cable assembly, are widely used for testing. We have the stainless steel version and the copper with gold plating version.
