Coaxial cable Options for U.FL cables

When choosing a coaxial cable for U.FL connectors, it’s essential to consider both physical space constraints and signal performance requirements. Below are the supported cable types with key characteristics:

1.13mm Mini-Coaxial Cable (50 Ohms)

• Diameter: 1.13mm
• Jacket: Black
• Key Feature: Extremely thin and flexible, ideal for tight internal spaces.
• Use Case: Best for applications where space is very limited, such as connecting a U.FL connector to a mini PCI card or embedded board. The thin diameter helps ensure the U.FL connector snaps securely onto the jack without dislodging.
• Note: Recommended for internal use only; not suitable for outdoor environments.

RG174 Coaxial Cable

• Diameter: Thicker than 1.13mm
• Jacket: Black
• Key Feature: Lower signal loss (attenuation) and better durability than 1.13mm.
• Use Case: Offers a balance of flexibility and performance. Suitable for both indoor and outdoor installations.
• Note: Higher quality translates into improved RF performance and reliability compared to thinner cables.

1.32mm Coaxial Cable (Double-Shielded)

• Diameter: 1.32mm
• Key Feature: Maintains a thin profile while offering enhanced shielding for reduced interference.
• Use Case: A great middle-ground solution when space is limited but improved shielding is required over 1.13mm.

Special Orders: We offer a range of options for the thickness of the coax, providing you with the flexibility to choose the most suitable for your needs. Our special orders include RG174, 1.13mm, 1.32mm, and 1.37mm coax, allowing you to opt for a lower-loss, thicker cable for the shorter versions of this cable. Feel free to contact us to discuss and make a special order that meets your requirements.

RP-SMA female connector includes a bulkhead nut and washer:

• This can be used to mount the connector (and thus the cable) on the wall of a network enclosure (to weatherproof the cable connection) or on a case, panel, or Printed Circuit Board (PCB).
• Weatherproofing: Our tried and tested method involves sealing the hole where the female connector is mounted by placing an O-ring between the enclosure's wall and the bulkhead nut and washer on the female connector. This ensures a reliable and secure weatherproof seal.

Our standard RP-SMA-female connector (threaded part) length is 3/8 inches. We also offer a longer option: 14.5mm. This extended option features an O-ring embedded in the flange, providing a waterproof port where the cable enters a network enclosure. Consider this option for enhanced weatherproofing in your network installation.

U.FL Connectors Characteristics

• The U.FL connector is also known as Ultra Miniature Coax Connectors (UMCC) and enables attaching an external antenna to a U.FL jack/connector on Printed Circuit Boards (PCBs): The U.FL female mates with a female Hirose/U.FL jack, also known as the U.FL-LP-66 jack/connector.
• U.FL male has a pin and is the connector: Male U.FL is the gender that is the "jack" embedded directly on to a circuit board on devices such as BlueTooth boards, ZigBee radios such as XBee, Printed Circuit Boards (PCBs), and internal mini-PCI wireless cards (even though the gender is male, it is the jack U.FL connector. Hence, the male connectors/jacks are very rigid.
• U.FL female has a socket. U.FL female right-angle type is the most common U.FL connector type found on U.FL cables: 95% of U.FL cables have a U.FL female right-angle connector.
• The size of U.FL connectors has made them an excellent fit in Machine-To-Machine (M2M) and IOT (Internet of Things) wireless applications since they take up very little space in the cramped cases of small devices, such as Bluetooth beacons.
• Gender Determination: Micro-connectors such as U.FL have a gender that is counter to typical RF terminology for gender, in that "jack" is more typically synonymous with "female": A U.FL jack on a board (PCB) is the male U.FL, and the connector that mates with the jack is the female.
• Connecting and disconnecting U.FL connectors from the jack can be difficult to do properly without damaging the connector or jack. We offer a U.FL insertion tool to enable you to connect/insert and remove/disconnect easily without causing any damage to the cable, connector, or jack.

U.FL Connectors' Material composition

• Male has a silver-plated phosphor bronze made the shell, and a gold-plated brass made contact.
• Female: The shell and contact of Female U.FL connectors are made of phosphor bronze but are silver—and gold-plated, respectively. Female U.FL connectors are used in terminating antenna cables.
• U.FL connectors are precision machined. The gold-plating enables low signal loss.

Compatibility with wireless protocols and applications:

Our RP-SMA "pigtail" cables are compatible with a wide range of wireless applications due to their frequency band compatibility (0GHz to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm cables. They support all WiFi standards, including 2.4GHz and 8GHz applications such as Wi-Fi HaLow 802.11AH, 802.11AX, 802.11AC, 802.11N, 802.11G, 802.11B, and 802.11A. Additionally, they are suitable for cellular wireless LTE / 4G, GSM / 3G, and WiMax for data and voice applications. Our cables also work with IoT wireless, automation, and Machine to Machine (M2M) applications like Bluetooth, ZigBee, WiFi HaLow, RFID, LoRa, LTE-m, and NB-IoT, WiFi 6, WiFi 6E.

RoHS 3 and REACH compliant: All of our antenna cables and RF adapters comply with RoHS 3 and REACH standards regarding the content limits of lead and other toxic materials.
