59--DIPLEXER

DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA MARITIME.DLA MARITIME COLUMBUS.DLA WEAPONS SUPPORT · Response deadline: Tue, 17 Nov 2026

What the government is buying

The Defense Logistics Agency (DLA) is seeking to procure a diplexer through its Weapons Support directorate at DLA Maritime Columbus. A diplexer is a radio frequency (RF) component used to combine or separate signals at different frequencies, enabling a single antenna to be shared for transmitting and receiving. These devices are commonly employed in military communications, radar, and electronic systems where spectrum efficiency and hardware consolidation matter.

This requirement falls under DLA's routine sustainment mission: supplying spare and repair parts to keep weapon systems and platforms operational. DLA Maritime supports Navy and Marine Corps fleets, as well as other Defense Department customers, with maritime-specific logistics. The "59" classification code indicates this is a Communication, Detection, and Coherent Radiation Equipment item in the federal supply classification system.

Key facts

Who can bid

Any responsible offeror may submit a bid—this is a full and open competition with no small-business set-aside. That said, small businesses in NAICS 334220 are encouraged to compete, as DLA has small-business participation goals even in unrestricted solicitations.

To bid, you must be registered in SAM.gov with an active Unique Entity ID, and your registration must reflect the appropriate NAICS code. If you manufacture diplexers or comparable RF filtering equipment, ensure your SAM profile and past-performance references align with communications hardware. DLA typically sources from both original equipment manufacturers and qualified distributors; check whether the solicitation specifies source acceptance or First Article Testing requirements.

How to put together a competitive bid

For DLA open-market buys, price is usually the dominant evaluation factor, but delivery performance and technical compliance determine eligibility.

• Verify specifications precisely: Diplexers are defined by frequency bands, insertion loss, isolation, power handling, and connector types. Obtain the Item Standardization Code (ISC) or military specification reference from the solicitation. Minor deviations can render a bid non-responsive.
• Confirm traceability and pedigree: DLA Weapons Support often requires items meeting military or aerospace standards (MIL-STD, MIL-PRF, or SCD). Document your manufacturing source, lot traceability, and any obsolescence management practices.
• Sharpen your pricing: Research recent DLA awards for comparable NSNs using SAM.gov's contract data or the DLA Internet Bid Board System (DIBBS) history. DLA's automated procurement systems favor best-value automated awards; aggressive, defensible pricing matters.
• Address delivery: State your quoted delivery schedule clearly. DLA evaluates bids against required delivery dates; inability to meet the government's need-by date can disqualify an otherwise low offer.
• Review packaging and marking: DLA has strict Military Standard packaging requirements. Non-compliant packaging is a common reason for bid rejection or post-award issues.
