PIP-II HPRF WR1150 Waveguide Directional Couplers for LB/HB650

The Fermi National Accelerator Laboratory is soliciting proposals for 55 WR1150 Waveguide Dual Directional Couplers designed to operate at a center frequency of 650 MHz with a 10 MHz bandwidth and 70 kW continuous wave forward power handling capability. The couplers must meet specific technical specifications including aluminum 6061 construction with RoHS-compliant coating, serialization with calibration information, and S-Matrix data. Fermilab has emphasized through a 10/31/2025 update that the couplers must sustain small differential air pressure to maintain acceptable non-ionizing radiation levels, minimize cross-talk between ports during operation for diagnostic purposes, and feature external terminations or replaceable internal terminations to facilitate repair and maintenance. The procurement will utilize best value source selection based on lowest price among technically acceptable offerors, with award intended without discussions. Proposals are due by 5 p.m. CST on November 7, 2025, and vendors must complete the RFP submission, SARC (Subcontractor Annual Reps & Certs), and PUR-466 (Proposal Certifications) forms.

This solicitation carries no set-aside designation and does not identify any incumbent contractors. Delivery must be completed within 20 weeks after receipt of order to the Fermilab Receiving Warehouse 2 in Batavia, Illinois, with F.O.B. Fermilab terms and all freight charges included in the quotation. The procurement requires vendors to comply with federal acquisition regulations, including export/import control certifications, Buy American provisions, anti-kickback procedures, and trafficking in persons regulations, with compliance requirements scaled to the proposal value. While no specific budget range is disclosed in the notice, offerors must anticipate costs associated with the manufacture and delivery of 55 specialized directional couplers along with required technical documentation. The place of performance is Batavia, Illinois 60510, and the procuring agency operates through Fermi Forward Discovery Group, LLC under Department of Energy Prime Contract No. DE-AC02-07CH11359.
