SMA Plug Connectors (Male) Guide
What Are SMA Plug Connectors (Male)?
Tyclon's male SMA plug connectors provide reliable, high-frequency performance for RF and microwave applications up to 18 GHz. With precision screw coupling, they deliver stable electrical performance, excellent impedance matching, low VSWR, and lasting mechanical strength. Available in multiple configurations, Tyclon's male SMA plug connectors maintain consistent signal integrity and durable construction for use in test instruments, communication systems, and general RF applications.
Mating of SMA Connectors
The SMA connector uses a threaded coupling mechanism to ensure a secure, reliable connection.
SMA Plug Connector (Male) by Type
Male SMA plug connectors feature a male interface on the mating side and connect to a coaxial cable on the opposite end. In the SMA connector series, two main plug configurations are available: straight plugs and right-angle plugs, offering flexibility for various installation layouts and space-saving requirements.
Trivia: Plug Receptacles
The designs of plugs and jacks vary depending on the type of coaxial cable used.
A similar connector that also attaches to coaxial cables is a receptacle. Receptacles can be mounted on any coaxial cable as long as the diameter of the connector’s center contact matches the diameter of the cable’s inner conductor. However, because receptacles do not connect to the cable’s outer sheath, the connection area is less robust. For this reason, they are typically used for internal wiring inside enclosures or devices.
Although most receptacles have a female interface, some SMA models feature a plug receptacle type with a male interface for specific applications.
Examples of SMA Plug (Male) Usage
Straight Plug (Male):
Connects directly without bending, making it simple and versatile for general use where space behind the device is not limited.
Right-Angle Plug (Male):
Useful when the jack (female) on your device is positioned so that a straight plug would be inconvenient. Ideal when equipment must be placed against a wall or in a tight space with little room behind it.
