## Summary description

Compact RF pigtail cable with U.FL female connector on one end and SMA male connector on the other, 20 cm length. Designed for connecting small wireless modules or antennas to SMA-equipped devices, it provides a secure coaxial connection for RF signals. Suitable for prototyping, IoT modules, routers and radio modules where bridging U.FL and SMA interfaces is required.

## Long description

Compact RF pigtail cable with a U.FL female connector on one end and an SMA male connector on the other, 20 cm length provides a reliable coaxial link for RF signals between small wireless modules and SMA-equipped devices. The cable is intended to bridge the miniature U.FL interface commonly found on IoT modules, Wi‑Fi and cellular modules, and embedded radio boards to standard SMA antenna ports. Its short, flexible form factor supports prototyping, lab use and permanent installations where a low-profile connection is required.
Advantages
The cable offers a secure electrical connection with low insertion loss appropriate for short RF interconnections. Its U.FL female connector is compact for space-constrained PCBs and modules, while the SMA male provides a robust threaded interface for external antennas and test equipment. At 20 cm length the pigtail balances reach and signal integrity, reducing cable clutter and minimizing additional attenuation compared with longer leads.
Suitable for
Connecting embedded Wi‑Fi, Bluetooth or cellular modules with U.FL to external SMA antennas
Prototyping and development with evaluation boards and radio modules
Router and gateway installations requiring a transition from U.FL to SMA
Laboratory testing, measurement and temporary RF connections
Key specifications
Connector type (end A): U.FL female designed for small form-factor RF modules
Connector type (end B): SMA male with threaded coupling for secure antenna attachment
Cable length: 20 cm
Cable form factor: flexible coaxial pigtail suitable for tight spaces
Typical application frequency range: suitable for common RF bands used by Wi‑Fi, Bluetooth and cellular modules (consult device requirements for exact limits)
Impedance: 50 Ω characteristic impedance for RF compatibility
How to use
Carefully align the U.FL female connector with the module’s U.FL jack and press straight down until it snaps into place; avoid excessive lateral force to prevent damage to the miniature socket. Thread the SMA male onto the corresponding SMA female port by hand until finger-tight, then use a torque wrench or appropriate tool if a specified torque is required by the equipment manufacturer. Route the 20 cm coaxial cable to avoid sharp bends and pinch points, and secure it with light clips or cable ties if needed to reduce mechanical stress on the connectors.
Usage recommendations
Verify compatibility of connector types and the device’s frequency band before installation. For permanent installations, avoid repeated mating cycles of the U.FL connector and consider using an adapter with a bulkhead SMA if frequent reconnections are expected. Keep bend radius gentle and protect the tiny U.FL socket from side loads to maintain reliable RF performance.
