Product Details
The SMA-WR90 is an X-band coax-to-waveguide adapter that transitions an SMA female coaxial connector to a WR-90 (UG-135/U) waveguide flange across the full 8.2 to 12.4 GHz band. It uses a square-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-90 waveguide components. It pairs directly with the AntenX WR-90 antenna line and serves as the reference adapter used to specify those antennas.
- SMA female to WR-90 (UG-135/U) coax-to-waveguide transition covering the full 8.2 to 12.4 GHz X-band waveguide range.
- Low insertion loss (typ 0.3 dB, under 0.5 dB) and VSWR below 1.5:1 (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-90 antenna line: SGH-WR90, EHA-WR90, and OEWG-WR90.
- Designed, assembled, and tested in California.
