SMA Jack Connectors (Female) Guide
What Are SMA Jack Connectors (Female)?
Tyclon’s SMA jack (female) connectors provide a dependable solution for coupling SMA interfaces in microwave systems, high-density PCBs, and demanding test and measurement applications. Manufactured with Japanese precision, they deliver excellent signal integrity and stable 50-ohm impedance control across a wide frequency range, typically up to 18 GHz.
Available in various configurations and mounting styles, our SMA jacks integrate seamlessly into antennas, filters, communication devices, and custom RF assemblies. Each connector is engineered for superior threaded coupling, ensuring robust resistance to vibration and reliable performance in critical applications. This design guarantees consistent connection quality and long-term usability in professional RF environments.
Mating of SMA Connectors
The SMA connector uses a threaded coupling mechanism to ensure a secure, reliable connection.
SMA Jack Connectors (Female) by Type
The SMA jack features a female interface on the mating side, while the opposite end is designed for connection to a coaxial cable. Within the SMA connector family, three primary jack types are available: straight jacks, bulkhead jacks, and flange jacks.
Trivia: Plug Receptacles
The designs of plugs and jacks vary depending on the type of coaxial cable used.
Example: SMA Plug for 3D-2V: SMAP-3A, SMA Jack for 3D-2V: SMAJ-3A
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.
A receptacle, like a jack, has a female opening. For more information on SMA receptacles, please see our product lineup
Note: Some "plug receptacles" with a male opening are also available.
SMA Jack (Female) Waterproof Type
This jack is suitable for both indoor and outdoor use, including areas near water, places exposed to rain or wind, or humid environments.
Examples of SMA Jack Connectors (Female) Usage
Bulkhead jacks and flange jacks are differentiated by how they are secured to the equipment chassis.
Bulkhead Jack:
The chassis is prepared with an opening sized for the connector body, and the connector is fastened by tightening a nut from the opposite side. Typically used where mounting space is limited or rapid assembly is required.
Flange Jack:
In addition to the main opening for the connector body, the chassis includes bolt or screw holes. The connector is secured using four mounting holes. Commonly used in applications requiring maximum mechanical stability and grounding reliability.
SMA Jack Connectors (Female) FAQs
QWhat is the primary purpose and orientation of the SMA jack (female) connector?
QWhat is the primary purpose and orientation of the SMA jack (female) connector?
The SMA jack is the female component that accepts the male SMA plug, facilitating the connection of internal circuitry to coaxial cables. It features a female interface on the mating end.
QWhat is the standard impedance rating for SMA female connectors?
QWhat is the standard impedance rating for SMA female connectors?
SMA female connectors are specifically engineered to maintain a 50 Ω impedance rating. This standardized value is critical for achieving optimal power transfer and minimizing signal reflection in radio frequency systems.
QWhat is the typical maximum frequency range for standard SMA jacks?
QWhat is the typical maximum frequency range for standard SMA jacks?
Standard SMA jacks are designed to operate effectively across a broad frequency spectrum, generally maintaining reliable performance up to 18 GHz. Higher frequency versions are also available for specialized needs.
QWhat method does the SMA connector family use to ensure a secure connection?
QWhat method does the SMA connector family use to ensure a secure connection?
SMA connectors utilize a reliable screw coupling mechanism (threaded coupling). This design ensures a robust and consistent connection, which is crucial for maintaining performance at microwave frequencies.
QWhat are the three main physical types of SMA jacks available for mounting?
QWhat are the three main physical types of SMA jacks available for mounting?
The three main types are the straight jack, the bulkhead jack, and the flange jack. These types support various installation methods, including PCB and equipment chassis mounting.
QHow does a bulkhead jack differ from a standard flange jack in terms of installation?
QHow does a bulkhead jack differ from a standard flange jack in terms of installation?
A bulkhead jack is mounted using a single nut that secures the connector through a prepared hole in the chassis. This method is often favored when mounting space is limited or rapid assembly is required.
QWhat is the installation benefit of using a flange jack (four-hole mount)?
QWhat is the installation benefit of using a flange jack (four-hole mount)?
A flange jack is secured using bolts or screws through four mounting holes in the chassis. This provides maximum mechanical stability and a highly reliable grounding connection for demanding applications.
