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

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.
