20cm RP-SMA Female to Stripping Head Cable RG1.13

An RP-SMA (Reverse Polarity SMA) connector has reversed gender roles for the center pin and socket compared to standard SMA. In an RP-SMA female, like on this cable, the connector has external threads and a center pin. This design is often used on consumer Wi-Fi equipment to prevent connection of high-gain external antennas that might violate regulatory limits, ensuring compliance with FCC and CE regulations.

The stripping head exposes the inner conductor and braided shielding of the coaxial cable. To use it, you typically solder the inner conductor to your target pad or antenna element and the shielding to a ground plane. Ensure a clean, short solder joint to maintain the cable's 50-ohm impedance. This method is ideal for permanent installations on PCBs or for attaching to custom whip antennas where a connector is not present.

The RG1.13 coaxial cable is designed with a characteristic impedance of 50 ohms, which is the standard for most Wi-Fi, cellular, GPS, and two-way radio systems. It is suitable for frequencies commonly used in IoT applications, typically up to several GHz. While performance varies, it provides a good balance of flexibility and signal integrity for short runs inside device enclosures or for prototype connections.
