Product Details
The SMA-WR137 is a C-band coax-to-waveguide adapter that transitions an SMA female coaxial connector to a WR-137 (UG-441/U) waveguide flange across the full 5.85 to 8.2 GHz band. It uses a round-flange, right-angle feed in a rugged all-metal body, with low insertion loss and low VSWR, making it a clean interface between coaxial test equipment and WR-137 waveguide components. It pairs directly with the AntenX WR-137 antenna line and serves as the reference adapter used to specify those antennas.
- SMA female to WR-137 (UG-441/U) coax-to-waveguide transition covering the full 5.85 to 8.2 GHz C-band waveguide range.
- Low insertion loss (typ 0.3 dB, under 0.5 dB) and VSWR below 1.6:1 (typically below 1.2:1).
- Rugged all-metal aluminum body with a stainless-steel SMA female connector; handles up to 20 W.
- Pairs directly with the AntenX WR-137 antenna line: SGH-WR137, EHA-WR137, and OEWG-WR137.
- Designed, assembled, and tested in California.
