A -- ADDITIONAL TOPIC TO BROAD AGENCY ANNOUNCEMENT (BAA)SOLICITATION NUMBER DAAB07-98-R-D003, UHF THREE CHANNEL MULTICOUPLER The Space and Terrestrial Communications Directorate is interested in receiving proposals for the design, development and fabrication of a three-channel UHF Multicoupler operating in the 225 MHz to 450 MHz frequency band for use in tactical Command and Control Vehicles (C2V) and other platforms to support on the move communications. The antenna Multicoupler must provide independent coupling of one (1) dedicated EPLRS wideband channel and two channels that will be able to work with either one (1) wideband NTDR radio or one (1) narrowband AN/ARC-164 radio. The Multicoupler shall provide cosite interference mitigation to reduce channel to channel coupling among the three radios connected to the UHF Multicoupler. The cosite interference mitigation techniques shall operate in spread spectrum environments such as Frequency Hopping Spread Spectrum, Direct Sequence Spread Spectrum or in combination of the two spread spectrum techniques. The proposed designs shall address the wide bandwidth operation and the cosite issues associated with the 3 multiplexed channels. The design shall incorporate cosite interference mitigation techniques such as frequency hopping filters and/or narrow-band/wide-band interference cancellation to reduce the cosite interference among the 3 radios connected to the UHF Multicoupler. The UHF Multicoupler's design must not place constraints upon the operational bandwidths of the UHF cosited radios, or resort to frequency management techniques based upon channel prioritization or other means to permit the simultaneous operation of the cosited radios. Proposals shall provide optional design consideration and trade-offs as related to the proposed solutions. The BAA shall also include comprehensive description along with block diagrams of the overall system design, RF power levels and interference product levels throughout the various RF signal paths. Deliverables: 1. A performance demonstration plan for the UHF Multicoupler shall be submitted for Government review. 2. Performance demonstration of the UHF Multicoupler at the contractor's facilities. 3. Two, three (3) channel UHF Multicoupler prototypes shall be delivered for government testing within eleven (11) month of contract award. The prototypes will initially be tested in a Government laboratory environment after which they will be tested in a field exercise. Accordingly the prototypes must be delivered in a ruggedized package to undergo armored platform field testing. 4. Final report, Deadline for Submission of Proposals: BAA proposals are to be submitted by 4:00 PM (1600 hrs), EDT on 15 September1998. Funding: This task is currently funded. It is the intent of S&TCD to leverage funding for this BAA via a 50/50 cost sharing program with potential bidders. Accordingly potential bidders are strongly encouraged to explore and reflect these opportunities in their BAA proposals. The Space and Terrestrial Communications Directorate is inviting potential BAA responders to a one-on-one meeting during the period of August 17 to August 28 1998 at CECOM Ft. Monmouth, NJ. This is an additional topic to the existing BAA, Solicitation Number DAABO7- 98RD003.
