Generic RP-SMA Female to Stripping Head Cable 10cm RG1.13

RP-SMA (Reverse Polarity SMA) reverses the gender of the inner conductor compared to standard SMA. An RP-SMA female has a center pin, while a standard SMA female has a socket. This design prevents standard SMA antennas from mating with RP-SMA equipment, often used for regulatory compliance on Wi-Fi routers. Always verify your device's port type (RP-SMA male/female) before purchasing cables to ensure compatibility.

First, separate the exposed central conductor from the surrounding shield braid. Tin both the conductor and a section of the braid with solder. On your PCB, solder the central conductor to the designated RF signal pad or antenna trace. Then, solder the shield braid to the ground plane adjacent to the signal pad, ensuring a short, direct connection. Avoid excessive heat to prevent melting the cable dielectric and maintain the 50-ohm impedance path.

RG1.13 coaxial cable is suitable for frequencies commonly used in IoT, including 2.4 GHz and 5 GHz Wi-Fi, sub-GHz LoRa (868/915 MHz), and cellular bands up to several GHz for 4G LTE. While insertion loss increases with frequency, this 10cm cable is effective for short runs within these bands. For precise high-frequency (e.g., 5G mmWave) or high-power applications, consult cable attenuation charts specific to RG1.13.

No, you cannot directly connect a standard SMA male antenna to an RP-SMA female port. This cable has an RP-SMA female connector, which is designed to mate with an RP-SMA male port (the common jack on many Wi-Fi routers). To adapt a standard SMA male antenna to an RP-SMA female port, you would need an RP-SMA female to SMA male adapter, not this stripping head cable.
