Basic information for 5 SMA connectors

What is the SMA Connector?

The SMA(SubMiniature version A) RF Connectors have a 50 Ohm impedance, which are are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling.

Originally SMA was designed for using from DC (0 Hz) to 12 GHz, however this has been extended over time and variants are available to 18 GHz and 26.5 GHz currently. The international screwing standard of SMA connector is Utilizes a one-quarter inch and 36 thread type coupler (SMA Female: 1/4-36UNS-2A; SMA Male:1/4-36UNS-2B)

How to identify the Gender of SMA Connector?

• SMA Male: Screw inside, center pin with needle
• SMA Female: Screw outside, center pin with hole
• RP-SMA Male: Screw inside, center pin with hole
• RP-SMA Female: Screw outside, center pin with needle

Different way to mount the SMA Connector

The SMA can be divided into mounting for Cable and PCB.

Designing a perfect SMA RF Connector

SMA RF connectors cater to diverse applications, from tailored single connectors ensuring seamless integration into existing systems to bespoke cable assemblies featuring multiple SMA connections and adapters, catering to a myriad of application requirements. While numerous SMA RF connectors in the market adopt a right-angle design, alternatives with straight angles are also available, contingent upon circuit specifications. The preference for right-angle designs stems from their role in maintaining the stability of impedance levels, as previously discussed.

Renhotec boasts an experienced engineering design team tasked with conducting exceptionally precise calculations of connector dimensions and structural components. Moreover, our production team operates with flawless precision during the assembly process, meticulously attending to the welding process. Excessive soldering can lead to impedance mismatch, a scenario that can also arise from dimensional inaccuracies, mechanical failures, or the presence of excess air surrounding connected components.
