Würth Elektronik RF coaxial antenna connector

The WR-UMRF ultra-miniature RF coaxial connector is Würth Elektronik’s compact high-frequency coaxial antenna connector.

The plug snaps into the jack to form a stable right-angled cable-to-board connection with a height of just 2.5 millimetres; this connection technology is of particular interest for connecting antennas to radio modules. The frequency range extends up to 6 GHz at 50Ω.

With a low height of 2.5 mm, the WR-UMRF is a slim connection solution, requiring a footprint of only 3.1 x 3.0 mm for PCB mounting. In terms of technical specifications, WR-UMRF remains compatible with many similar products on the market.

Würth Elektronik also offers pre-assembled cables with various combinations of UMRF, SMA or RP-SMA — optionally with protection class IP67. The available cable diameters are 1.13, 1.32 and 1.37 mm.
