U.FL-Male to SMA-Female RF Adapter Connector

High-Frequency, Precision Interface

Adapter for antenna Cable: SMA Female to U.FL-male

  • See also our U.FL-male To SMA cables.
  • One end has a U.FL male connector and the other end has a SMA female straight connector.

Compatibility with wireless protocols and applications:

Wireless System Compatibility:
This antenna cable adapter is optimized for broadband use (0GHz to 18GHz), ensure low VSWR, and feature a 50 Ohm impedance match, making them ideal for:

This compact SMA-female to U.FL-male adapter offers a reliable solution for connecting standard SMA interfaces to miniature U.FL connectors. Engineered for high-frequency applications, it ensures minimal signal loss and robust mechanical stability, making it ideal for wireless modules, embedded systems, and RF testing environments.

Key Features:

  • Connector A: SMA Female (Jack) – Threaded interface for secure connections
  • Connector B: U.FL Male (Plug) – Snap-on micro coaxial connector suitable for high-density PCB layouts
  • Impedance: 50 Ohms – Ensures compatibility with standard RF systems
  • Frequency Range: DC to 6 GHz – Supports a wide spectrum of wireless applications
  • Construction: Gold-plated contacts for enhanced conductivity and corrosion resistance
  • Applications: Ideal for Wi-Fi, Bluetooth, GPS, and cellular modules requiring SMA to U.FL interfacing

Applications:

This adapter is commonly used in scenarios where a device with an SMA connector needs to interface with a U.FL-equipped module. Typical applications include:

  • Connecting external antennas to mini PCIe wireless cards
  • Integrating GPS modules with SMA-based antenna systems
  • Facilitating RF testing setups requiring SMA to U.FL transitions

Installation Notes:

The U.FL connector is designed for limited mating cycles (typically around 30), so it's recommended for semi-permanent installations. Ensure proper alignment during connection to prevent damage to the delicate U.FL interface.

U.FL Connectors Characteristics

  • U.FL female has a socket. U.FL male has a pin and is the connector that is the "jack" on a devices such as Bluetooth boards, and 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.
  • U.FL connectors are widely used in M2M and IOT (Internet of Things) wireless applications.
  • 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.
  • Gender Determination: Micro-connectors such as U.FL have 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 U.FL 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 connector is also known as Ultra Miniature Coax Connectors (UMCC), and enables attaching antenna to a U.FL jack/connector on PCBs: U.FL female mates with a female HiRose/U.FL jack, also known as U.FL-LP-66 jack/connector.
  • U.FL connector is precision machined and gold-plated brass for low signal loss.
