Hirose, a leader in the design and manufacture of innovative connector solutions, has enhanced its compact coaxial connector offering to serve the emerging mobile and portable device market. The U.FL(A) coaxial connector is suitable for a wide range consumer, industrial, telecommunication and other applications that require high-frequency connectivity in a compact footprint.

Measuring only 2mm x 2mm with a 2.1mm mated height, the U.FL(A) Series connector meets the industry requirements for miniaturization and high-performance. Delivering high signal integrity and low insertion loss, the U.FL Series features low reflection characteristics up to 18GHz. 

The U.FL(A) Series has low voltage standing wave ratios (VSWR) of:

DC to 3GHz 3 to 6GHz : 1.3 Max. 

3 to 6GHz : 1.4 Max.

6 to 9GHz : 1.5 Max.

9 to 12GHz 12 to 15GHz : 1.6 Max. 

12 to 15GHz :  1.7 Max. 

15 to 18GHz : 2.0 Max.

Simplifying installation, the U.FL(A) Series offers features a self-alignment design that ensures stable and secure mating. In addition, a clear tactile click communicates proper mating to the installer.             

“Hirose invented the industry standard U.FL connector design that is used globally in wireless technology. The U.FL(A) Series is the latest example of Hirose’s commitment to developing innovative connector versions that solve design challenges for customers around the world,” says Mark Kojak, Sr. VP of Sales and Marketing for Hirose Electric USA.

Applicable shielded cable for the U.FL(A) includes 30 AWG (ø1.37 mm diameter) or 32 AWG (ø1.13 mm diameter).

The U.FL(A) Series is commonly used in PDAs, laptops and tablets, portable monitoring devices, and more.
