Variations of SMA Coaxial Connectors
SMA connectors come in several variations to cater to specific needs:
1. Standard SMA Connectors
Commonly used in general RF applications.
Frequency range up to 18 GHz, extended up to 26.5 GHz in some designs.
Available in male and female versions, plugs, and jacks.
2. Reverse Polarity SMA (RP-SMA) Connectors
Gender of the center pin and sleeve is reversed.
Designed to comply with regulatory requirements, especially in Wi-Fi equipment.
Prevent unauthorized antenna modifications that could violate FCC regulations.
3. Precision SMA Connectors
Designed for metrological applications requiring higher repeatability and accuracy.
Often use air dielectric instead of PTFE.
Compatible with higher-frequency SMA-like connectors such as 3.5 mm and 2.92 mm connectors.
4. Edge Launch and End Launch SMA Connectors
Designed for PCB mounting.
Facilitate high-frequency signal transitions from PCB traces to coaxial cables.
