2. IPEX Generation 3 to SMA Design for Flexible Antenna Connections

With the continuous development of wireless communication technology, compact RF connectors are increasingly used in wireless modules and electronic devices. IPEX connectors are commonly found in compact wireless modules because of their small size and suitability for internal installation.

SMA connectors, on the other hand, are widely used for external antennas, wireless communication equipment, RF systems, and other antenna-related applications.

The Kinghelm KH-IPEX3-SMAKWE5-RG0.81-B0160H provides a convenient connection between these two interface types. It allows an internal IPEX Generation 3 RF port to be extended to an external SMA interface, making it easier to connect an external antenna.

This design gives equipment designers greater flexibility when arranging antennas. The SMA connector can be mounted on an equipment enclosure or panel, allowing the antenna to be positioned according to the structural requirements of the device.

For products requiring external antennas, this IPEX-to-SMA RF cable assembly provides a practical interface conversion solution.

3. Gold-Plated SMA Female Connector with Stable Mounting Structure

The cable assembly uses a gold-plated SMA female connector with a four-leg semi-threaded structure. The connector also features a groove and a 5 mm threaded length.

SMA connectors are widely used in RF applications due to their compact size and broad compatibility with many antenna and communication systems. They are commonly used in wireless communication products, RF equipment, antenna systems, and electronic devices requiring external RF connections.

The four-leg structure is suitable for applications requiring connector mounting and fixation. The grooved connector design and 5 mm threaded section allow the product to meet corresponding panel-mounting and enclosure installation requirements.

Gold plating on the connector helps provide good contact performance and corrosion resistance. This makes the connector suitable for RF applications where stable electrical contact and reliable mechanical connection are important.

4. RG0.81 Black Coaxial Cable for Compact Internal Wiring

The KH-IPEX3-SMAKWE5-RG0.81-B0160H uses RG0.81 black coaxial cable for RF signal transmission.

Internal space is often limited in wireless communication devices and compact electronic products. Therefore, an RF cable must not only provide the required connection between the module and antenna interface but also support efficient cable routing within the device.

The relatively compact RG0.81 cable is suitable for internal RF connections in space-constrained equipment. Designers can route the cable between the wireless module and the external SMA connector according to the internal structure of the product.

The black cable provides a simple and practical appearance and can be easily integrated into different electronic device designs.

5. 160 mm Cable Length for Flexible Equipment Layout

Cable length is an important factor when selecting an RF cable assembly. A cable that is too short may not provide sufficient distance between the wireless module and the external connector, while an unnecessarily long cable may make internal routing more complicated.

This product features a cable length of 160 mm, or 16 cm, making it suitable for a variety of compact and medium-sized electronic devices.

The 160 mm length provides installation flexibility for connecting an internal IPEX Generation 3 interface to an SMA connector mounted on an external panel or equipment enclosure.

This length can be suitable for applications such as wireless communication terminals, IoT devices, Wi-Fi equipment, industrial communication products, and other electronic systems requiring external antenna connections.

6. Rated Voltage of 300 V

The Kinghelm KH-IPEX3-SMAKWE5-RG0.81-B0160H has a rated voltage of 300 V.

When selecting cable assemblies for electronic equipment, users should consider not only connector compatibility and cable dimensions but also the electrical requirements of the application.

The 300 V rated voltage provides a basic electrical specification for product selection. Users should still evaluate the specific operating environment and system requirements to ensure that the cable assembly is suitable for the intended application.

7. Wide Range of Applications

8. Important Considerations for Product Selection

When selecting an IPEX-to-SMA RF cable assembly, users should first confirm the generation and type of the IPEX connector used on the wireless module. Different connector generations and specifications may have different mechanical structures and dimensions.

For this product, the device-side interface should be confirmed as IPEX Generation 3 before installation.

Users should also verify the SMA connector requirements, including the connector gender, mounting method, threaded length, and equipment panel thickness.

The Kinghelm KH-IPEX3-SMAKWE5-RG0.81-B0160H uses a gold-plated four-leg semi-threaded SMA female connector with a groove and a 5 mm threaded length, so the equipment structure should be checked to ensure compatibility.

In addition, the 160 mm cable length should be evaluated according to the internal layout of the device. Designers should consider routing distance and available installation space to ensure proper cable placement.
