Product Overview
Reverse-Polarity Design for Easy Connector Matching-This RP-SMA connector has a female threaded body with a center pin, following the standard reverse-polarity configuration. Since RP-SMA and standard SMA connectors can look very similar, checking the mating connector before ordering is important to ensure the correct fit and avoid connection problems.
Right-Angle Structure for Space-Saving PCB Mounting-The right-angle design keeps the coaxial connection parallel to the PCB, which works well for board-edge and enclosed RF applications. It has an 8.5 mm thread, 14.5 mm overall length, and 13 mm height above the board, with 4.2 mm pin spacing and four 0.9 mm grounding posts. This compact layout makes it a practical SMA PCB connector where installation space is limited.
Copper Construction with Gold Plating and PTFE Insulation-Made from machined copper with gold plating and a PTFE insulator, this RF coaxial connector is built for stable RF connections and long-term use. The connector offers 5000 MΩ minimum insulation resistance, 1000 V withstand voltage, and an operating temperature range of −55°C to +155°C.
Through-Hole Mounting for Secure Soldering-The four square grounding posts pass through the PCB and provide a solid mechanical connection after soldering. They also help keep the RP-SMA connector from turning when the mating plug is tightened. Wave soldering is suitable for volume production, while hand soldering works well for samples and small batches.
Different Connector Options for Flexible Designs-The same basic design is available as an RP-SMA female right angle PCB mount connector, standard SMA female version, and other straight or offset-leg configurations. This gives engineers more options when the connector type or mounting direction changes without having to redesign the entire PCB.

Application
IoT Gateways & Edge Routers-An RP-SMA PCB connector for IoT gateway hardware connects the PCB directly to an external RP-SMA antenna without an adapter. The board-edge, through-hole design keeps the port aligned with the enclosure opening and provides good mechanical support. A standard SMA version can also be used for other product variants.
Wireless Routers & Access Points-Wireless routers and access points often use RP-SMA ports for external antennas, making connector compatibility an important design detail. This RP-SMA connector keeps the RF connection direct, while the right-angle design saves space behind the enclosure. Through-hole mounting also helps handle repeated antenna connection and removal.
RF Test Equipment & Bench Fixtures-RF test fixtures are connected and disconnected frequently, so the connector needs to hold up to repeated use. The gold-plated body, PTFE insulation, and through-hole mounting make this RF coaxial connector a good fit for test boards and bench equipment. It can also be desoldered and replaced when a fixture needs to be rebuilt.
Wireless Modules & Radio Boards-Wireless modules need a connector that matches the antenna and cable used in the final product. This RP-SMA female PCB through hole connector provides a compact board-edge connection and keeps the RF path direct. It works well for radio modules, communication boards, and embedded wireless equipment where connector polarity and PCB fit matter.
Custom Cable Assemblies & Panel Equipment-For board-to-panel RF connections, the connector can be supplied with a custom cable assembly to match the equipment interface. Cable length, connector type, plating, and labeling can be customized as needed. Both SMA PCB connector and RP-SMA versions are available for different antenna and equipment configurations.
FAQ
Q1. How can I tell RP-SMA from standard SMA?
The easiest way is to look at the center contact. This RP-SMA connector has a pin inside a female, externally threaded body, while a standard SMA female jack has a socket. Since the two can look almost identical from the outside, it is worth confirming the mating connector before ordering. If you are not sure which version you need, just send us the part number or a photo and we can help identify it.
Q2. Will this RP-SMA connector fit my PCB?
The main dimensions to compare are the 4.2 mm pin spacing, four 0.9 mm square grounding posts, 13 mm height above the PCB, and 8.5 mm thread length. The connector is 14.5 mm overall, with a right-angle design that keeps the coaxial connection parallel to the board. This RP-SMA female PCB through hole connector uses through-hole mounting posts, so the footprint and board clearance can be checked directly from the drawing. DXF and STEP files are available for design verification.
Q3. What are the frequency range and RF specifications?
This RP-SMA connector features a 50 Ohm design with a PTFE insulator, 5000 MΩ minimum insulation resistance, 1000 V withstand voltage, and an operating temperature range of −55°C to +155°C. The actual frequency range, VSWR, and insertion loss can vary with the PCB layout, cable, and mating components. If you share your operating band, we can provide the relevant test data for your application.
Q4. Is a standard SMA version or a custom configuration available?
Yes. Along with the RP-SMA version, we offer standard SMA configurations in right-angle, straight, and offset-leg designs. Custom options such as cable assemblies and plating are also available for different PCB and equipment requirements. If you are developing several versions of the same product, the SMA PCB connector and RP-SMA options can be matched to the same basic design where possible.
