Description
Product Overview
The Proxicast U.FL (IPEX / MHF1) to SMA Female jumper cable is engineered for high‑frequency applications up to 6 GHz. Each 8‑inch (20 cm) pigtail features a 1.37 mm (0.054 in) coaxial core with a 50 Ω impedance, constructed from solid silver‑plated copper for the center conductor and gold‑plated pins for optimal conductivity. The outer shield is tin‑lined copper, providing excellent shielding against EMI. Packaged in a flat free package (FFP), the two‑piece set weighs only 4 g per cable, making it lightweight and easy to route within tight enclosures.

Usage
Designed for indoor networking equipment, this cable connects U.FL male ports on PCIe, mPCIe, or other circuit boards to SMA female bulkhead jacks for external antennas or test equipment. Ideal for hobbyists, engineers, and IT professionals installing Wi‑Fi, LTE, or 5G modules, it ensures low signal loss in compact devices such as routers, modems, and RF development kits.
Why Choose Us
Proxicast adheres to RoHS standards, guaranteeing an environmentally friendly product. The combination of silver‑plated copper core, gold‑plated pins, and tin‑lined shielding minimizes insertion loss and maximizes durability. Each cable undergoes strict quality testing to meet a maximum voltage rating of 200 V and a frequency response up to 6 GHz, ensuring reliable performance in demanding networking environments.

No. M.2 modules typically use the MHF4 connector interface, which is not compatible with this U.FL to SMA jumper.
What is the maximum frequency supported?
The cable is designed to operate reliably up to 6 GHz, making it suitable for most Wi‑Fi, LTE, and emerging 5G applications.
Is the cable suitable for outdoor use?
This product is intended for indoor use only. For outdoor installations, a weather‑rated coaxial cable should be selected.
How many cables are included in the package?
Each SKU includes two 8‑inch cables, providing a convenient 2‑pack for dual‑antenna setups.
What devices are compatible with this jumper?
It works with modems, RF modules, radio add‑in cards, routers, and any equipment featuring a U.FL male connector that requires an SMA female connection.
