When designing RF equipment solutions, selecting a stable and reliable connector can be quite challenging. You may have encountered issues like loose threading, unstable board-end soldering, difficult assembly, or fluctuating performance. These problems often only appear on-site, causing unnecessary rework and losses. The KH-SMA-KWE14-T from Kinghelm is meticulously designed to solve these "user pain points" as an SMA female board-end RF connector.

It features a 14-thread standard SMA threaded interface with a female structure and a right-angle design, suitable for board-end applications with limited lateral space. Secure soldering, smooth plugging/unplugging, and stable connection without looseness are the basic requirements engineers care about most. This product is optimized in detail — a stepped structure at the connection point allows for automatic positioning during assembly, resulting in more precise soldering and long-term stability without loosening or misalignment. Many customers have reported that this design saves considerable trouble when moving from small to large batches.

The main body is made with careful material selection; the shell is generally made of gold-plated or nickel-plated copper, and the contact parts are gold-plated for corrosion resistance and good conductivity. Whether you are working on communication modules, antenna interfaces, or automotive and industrial control equipment, this connector fits well. It supports frequency ranges from DC up to 18 GHz, performing stably within this bandwidth. Signal consistency, insertion loss, and VSWR all meet high engineering standards.

In terms of weight, the KH-SMA-KWE14-T SMA female connector is only 5.51 grams per piece, facilitating lightweight designs for the whole device. It comes in tray packaging suitable for automated assembly lines, saving manual placement time. Kinghelm applies mature manufacturing processes; each batch undergoes plug-in durability, high-frequency characteristics, and environmental adaptability tests, ensuring every connector you receive is “plug and play” with no trial-and-error costs.

This connector has a wide range of applications, extending beyond traditional communication equipment. It is now commonly found in emerging fields such as vehicle OBD diagnostics, Beidou navigation modules, smart gateways, drones, and industrial IoT devices. Its compact structure offers stable connections, works reliably across environments, and provides some resistance to vibration and interference — ideal for projects demanding “stability, reliability, and no failures.”

As a professional brand in the RF connection technology field in China, Kinghelm has always focused on practicality and engineering feasibility. We understand that users care not only about specifications but also about installation convenience, long-term stability, and consistent delivery. The KH-SMA-KWE14-T has been thoroughly engineered with these aspects in mind.
