L-com CA-RSPRSJA004 4 ft RP-SMA Coaxial Extension Cable
The L-com CA-RSPRSJA004 is a 4 ft low-loss RF cable assembly with an RP-SMA plug at one end and an RP-SMA jack at the other. Its plug-to-jack configuration provides additional reach for compatible antenna and radio connections.
Built with 50-ohm 195-Series coaxial cable, this assembly is intended for wireless LAN, external antenna, and other properly matched RF applications. The compact cable format helps accommodate installations where equipment placement requires a short extension.
Key Features
- Exact manufacturer model: CA-RSPRSJA004.
- 4 ft nominal cable length.
- Reverse-polarity SMA plug-to-jack configuration.
- Straight connectors at both ends.
- 50-ohm low-loss coaxial construction.
- Black PVC cable jacket.
RP-SMA Connectivity
The RP-SMA plug connects to a corresponding RP-SMA jack, while the cable's RP-SMA jack accepts a corresponding RP-SMA plug. Verify both the connector body and center contact before installation; standard SMA and RP-SMA are different interfaces.
RF Installation Planning
Confirm that the complete assembly meets the installation's frequency, power, and insertion-loss requirements. Account for the additional cable length and connector junctions when calculating the RF link budget.
Ideal Applications
- Compatible external antenna extensions.
- Wireless LAN equipment installations.
- RF connections between nearby equipment locations.
- Wireless OEM integration requiring an RP-SMA plug-to-jack cable.
Compatible Products
The CA-RSPRSJA004 is intended for compatible 50-ohm RF systems requiring an RP-SMA plug-to-jack extension.
- RP-SMA plug end: Plug body with a female center socket; mates with an RP-SMA jack.
- RP-SMA jack end: Jack body with a male center pin; mates with an RP-SMA plug.
- System requirements: Verify operating frequency, RF power, impedance, connector polarity, and allowable total signal loss.
Important: Standard SMA and RP-SMA connectors use different center-contact arrangements. Similar threads do not establish compatibility. Do not select this cable for N-type, RP-TNC, BNC, or proprietary interfaces without a correctly specified adapter arrangement.
Do not assume compatibility with a particular Wi-Fi band or radio solely because its antenna connector fits.
