2 Directional Couplers

The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is seeking information from industry sources regarding the procurement of two high-power dual directional couplers. These couplers are essential for measuring high-power RF waveforms, which are critical in semiconductor plasma processing, impacting the quality of semiconductor chips. NIST aims to close the measurement gap in high-power waveform metrology, with supplies anticipated to be required by June 1, 2026. Interested parties should submit their responses by December 8, 2025, to Elizabeth Timberlake at elizabeth.timberlake@nist.gov and Donald Collie at donald.collie@nist.gov, adhering to specified submission guidelines.
