Three plans support SMA board design and facilitate the development of IoT products.

IoT products, which connect and exchange data with a network of various things, require wireless communication. For this communication, it is common to adopt an antenna module and connection method that meets the wireless communication standard LPWA (Low Power Wide Area). The "FL CoaxBridge" uses Hirose’s SMA antenna connector and can meet the LPWA standard while reducing space and cost. Additionally, you can choose from three connection plans to meet your board design needs.

Features of HIROSE’s SMA-U.FL Connection
Space-Saving
U.FL occupies 7.7mm² on the board. Although U.FL is very small, it has a clear locking feel that reliably confirms mating. Receptacles can be automatically mounted with embossed taping packaging. The cable has an outer diameter of MAX φ1.37mm and can be wired in a small space.
Low Cost
Excluding the outer shell, and the harness process are standardized.
High Frequency Characteristics
Reflection of cable connection is minimized to achieve high frequency performance of 8GHz.
You can choose from 3 plans according to the board design.
Plan Comparison
Plan A (Adjustable Cable Assembly Length) | Plan B (Cable Assembly that Reduces Labor Time) | Plan C (For Strengthened Ground Connection with the Board) | |
---|---|---|---|
Board Design | Excellent Easier board design |
||
Support for Design Changes and Reproduction | Excellent Minimal number of parts to change (Can adjust the U.FL harness length without changing the body) |
Good Supported by using different length cable assemblies |
Poor U.FL plug Both ends harness product can be changed in length, rework required |
Wire Routing Flexibility | Excellent There are no restrictions on the mounting position of the housing and the position of the board inside the housing. |
Poor Board position in the housing is limited |
|
Others | - | - | Excellent Ground connection is possible directly below the panel. |
Plan A (Adjustable Cable Assembly Length)
You can adjust the length of the double-ended U.FL Plug assembly by yourself. This type allows signals to flow to various parts on the board and increases design freedom.

■ SMA-U.FL Conversion Adapter
BNC to D.FL conversion adapters are also available for 75Ω applications. Please refer to the Digital Catalog for details.

Plan B (Cable Assembly that Reduces Labor Time)
Since the U.FL plug is already harnessed to SMA, assembly is completed in the following 2 steps: 1. Secure the SMA to the case with a nut, 2.Mate U.FL. This type reduces man-hours.
