MHF4 to RP-SMA Cables

  • The largest diameter of coaxial cable that the MHF4 connector can accommodate is 1.13mm:  Therefore all of our standard RPSMA to MHF4 cables are made with 1.13mm coax.   We can use 0.81 coax in special orders.

Antenna Cables

RP-SMA to MHF4 cables are designed to bridge between RP-SMA connectors, commonly used in Wi-Fi routers, antennas, and RF equipment, and MHF4 connectors, often found on the printed circuit boards of miniaturized devices like laptops, tablets, or IoT devices. Here's a detailed look at these cables:

  1. RP-SMA Connector:

    • This is a variant of the standard SMA (SubMiniature version A) connector but with reverse polarity. In RP-SMA connectors, the gender of the interface is reversed compared to the standard SMA. This means the male connector has a center socket instead of a center pin, and the female connector has a center pin instead of a center socket.

  2. MHF4 Connector:

    • MHF4 connectors are ultra-miniature RF coaxial connectors. They are the smallest mini RF connectors in the market. Due to their small size, they are typically used in applications where space is limited, such as in laptops, tablets, smartphones, and other compact wireless communication devices.
    • These connectors are designed for high-frequency applications and provide excellent RF performance.

  3. Cable Specifications:

    • RP-SMA to MHF4 cables feature an RP-SMA connector on one end and an MHF4 connector on the other.
    • The largest diameter of coaxial cable is 1.13mm, because this is the biggest diameter that the MHF4 connector can accommodate. 
    • Designed to carry high-frequency signals with minimal loss. The length of the cable can vary depending on the application, but shorter lengths are generally preferred in RF applications to minimize signal loss.

  4. Applications:

    • These cables are commonly used in wireless communication systems where there is a need to connect a device with an MHF4 interface (like a Wi-Fi module inside a laptop or tablet) to an external antenna with an RP-SMA interface.
    • They are particularly useful in custom Wi-Fi setups, DIY IoT projects, or in situations where internal wireless cards in laptops or other devices are being upgraded or connected to larger external antennas for improved range and signal quality.

  5. Installation and Usage Considerations:

    • When using these cables, it's essential to ensure proper connection and tightening to avoid signal loss.
    • Also, care should be taken to avoid excessive bending or stretching of the cable, as this could damage the internal coaxial structure and degrade performance.
