The Naval Research Laboratory in Washington, DC seeks quotations for brand-name-only new amplifiers—10–1000 MHz, 13 dB, +26.5 dBm, connectorized (H1), and 50–250 MHz, 17 dB, +33.5 dBm, SMA—with no remanufactured or gray-market items and OEM warranty coverage. This is a total small business set-aside, firm-fixed-price procurement under NAICS 334419, and offerors must be the OEM or an OEM-authorized dealer, distributor, or reseller and provide manufacturer authorization documentation for the specific items. Delivery is to NRL at 4555 Overlook Avenue SW, Building 49, Washington, DC 20375, with FOB destination preferred; any maintenance-renewal performance period must begin on or after award and cannot be backdated, with reinstatement fees listed separately. Award will be made on a lowest-price technically acceptable basis, potentially without discussions, so offerors should have active SAM registration and must submit one technical and price quote by email with DUNS and CAGE codes. Quotations must state whether the solicitation terms and conditions are accepted without modification or list exceptions with rationale.
