RP-SMA Female Input to Dual RP-SMA Female Output T-Type RF Connector Splitter

In the realm of radio frequency (RF) communications, two prevalent types of coaxial connectors are SMA (SubMiniature Version A) and RP-SMA (Reverse Polarity SMA). Here's a detailed look at these two connectors:

1. SMA (SubMiniature Version A) Connector

Definition: SMA connectors are compact coaxial connectors engineered for superior performance across a broad frequency range, typically spanning from 0 to 18 GHz.Applications: These connectors find extensive use in radio systems, Wi-Fi antennas, microwave applications, radio transmitters, GPS systems, RF circuits, and high-frequency testing equipment.Design: SMA connectors are available in both male and female variants. In a standard SMA connector:
 

• The male connector features an outer threaded coupling and an inner pin serving as the center conductor.
• The female connector possesses an inner socket for the center conductor and an outer threaded section to connect with the male.

Advantages: SMA connectors offer low signal loss at high frequencies, boast a robust mechanical design, are compact in size, and have a wide range of applications.

2. RP-SMA (Reverse Polarity SMA) Connector

Definition: RP-SMA is a variant of the SMA connector with reversed polarity. The mechanical design is modified, reversing the gender of the inner conductor while maintaining the standard threading of the outer shell.Difference: The primary distinction between SMA and RP-SMA connectors lies in the gender of the inner conductor:
 

• SMA Male: Features outer threads and an inner pin.
• RP-SMA Male: Has outer threads and an inner socket (replacing the pin).
• SMA Female: Lacks outer threads and has an inner socket.
• RP-SMA Female: Lacks outer threads and has an inner pin (replacing the socket).

Applications: RP-SMA connectors are widely employed in Wi-Fi antennas, wireless routers, Bluetooth devices, and various RF applications. Manufacturers often use them to prevent the connection of non-compliant antennas.Regulation: Reverse polarity is frequently used to ensure devices adhere to regulatory standards, such as those set by the FCC, by preventing the use of incompatible antennas.

Summary:

SMA Connector: Standard polarity with the male variant featuring a pin and the female variant featuring a socket. It is utilized in a wide array of RF applications.RP-SMA Connector: Reverse polarity, with the male variant featuring a socket and the female variant featuring a pin. It is commonly used in Wi-Fi applications and is designed to prevent the use of incorrect antennas.Both connectors provide reliable, low-loss connections at high frequencies. However, RP-SMA introduces an additional layer of compatibility control by reversing the gender of the inner conductor.
