In RF device design, connectors may be small in size but are indispensable components for reliable signal transmission. As modern devices increasingly trend toward miniaturization and integration, higher demands are placed on connector size, structure, and electrical performance. The Kinghelm KH-SMA-P-8496-T 11-thread right-angle SMA female PCB connector is a practical product that balances space-saving with stable connectivity, ideal for a variety of RF modules and high-frequency interface applications.

This connector features a right-angle design, with the interface extending from the circuit board at a 90-degree angle. This structural layout effectively reduces vertical height, making it highly useful for terminal devices with limited internal space. Common use cases include RF transceiver modules, embedded wireless communication boards, and miniature antenna interfaces—where this right-angle configuration facilitates edge mounting and neat cable routing.

Beyond its compact structure, it boasts a key advantage: a stepped interface design. This feature ensures better positioning during soldering and prevents loosening during insertion and removal. For devices that require long-term operation and may experience mild vibrations—such as portable antenna modules or outdoor communication enclosures—the stepped structure provides a more secure connection, minimizing the risk of contact failure.

The product adopts a standard SMA female interface with threaded fixation (11 threads), compatible with most SMA male connectors on the market, facilitating device interoperability and maintenance. It supports a wide frequency range suitable for transmitting Wi-Fi, Bluetooth, GPS, cellular signals, and other RF communications, meeting the connection needs of most mid-to-high frequency modules.

Packaged as a right-angle PCB mount connector, it is easy to solder without the need for additional wiring or custom cables, making it especially convenient for rapid prototyping during product development. The product comes in a flexible pack of five pieces, allowing engineers to purchase and replace according to demand. Each piece weighs only 3.964 grams, adding negligible weight to the device, which is particularly advantageous for lightweight applications such as drones and portable communication equipment.

Notably, the KH-SMA-P-8496-T is a standard model in Kinghelm’s RF connector lineup, offering stable long-term supply and strong compatibility. Whether used as the mainboard-to-external antenna interface or for high-frequency signal transmission between modules, it delivers a clear, low-loss connection path, making it a reliable RF connection solution.

In summary, the Kinghelm KH-SMA-P-8496-T is a well-balanced SMA female PCB connector in terms of structure and performance. It is compact, robust, and easy to solder, suitable for both small-batch product development and large-scale production. For projects that require excellent RF performance while facing space constraints, this connector is a practical and worthwhile choice.
