DPA26BZ02-NV007 — Compact Wideband Tunable Filters
Award Maximum: $250,000 Period of Performance: 6 months Phase Type: Phase I
OBJECTIVE: Develop and demonstrate wideband, power-efficient and tunable radio frequency (RF) filter technologies that significantly improve spectrum access and signal integrity for Department of War (DOW) communications and electronic warfare (EW) systems.
DESCRIPTION: The DoW relies heavily on RF communications and EW systems for critical tactical operations. Current filters often struggle to provide sufficient bandwidth, selectivity, and agility to operate effectively in congested electromagnetic environments. The increasing use of the RF spectrum, coupled with the growing sophistication of adversarial electronic attacks, necessitates advanced RF filtering technologies. The DARPA Wideband Adaptive RF Protection (WARP) program is developing advanced filter and canceller technology to protect wideband receivers from external and self-interference. This Small Business Innovation Research (SBIR) opportunity seeks innovative solutions for wideband tunable microwave filters that offer superior performance in bandwidth, insertion loss, rejection, size, and power. The focus is on protecting wideband receivers from external interference and jamming.
PHASE I: Phase I is a 6-month effort focused on designing and modeling a compact, wideband filter with a center frequency tuning ratio equal to or greater than 4 to 1 in the frequency range of 2 to 18 GHz, and a bandwidth tuning of at least 3 to 1. The mode of operation may be bandpass, bandstop, or preferably both modes. Phase I will demonstrate the viability of the proposer's technical approach. This will include analytical feasibility studies and modeling showing the proposed solution can meet the filter technical metrics listed in Table 1. Simple experimental demonstrations may also be included to help support the proposed concept. Deliverables for Phase 1 include quarterly financial reports; a kickoff technical report; an interim technical report; a final detailed technical report outlining the proposed technology and how it compares with existing commercial filters; proof-of-concept analysis and/or simulations; a preliminary filter design; a fabrication process; a risk assessment and mitigation strategy; a detailed Phase II work outline; and a commercialization plan outlining target markets, strategy, and potential DoW insertion opportunities. There will also be a kickoff meeting, quarterly meetings, and a closeout meeting.
Phase I fixed payable milestones for this program should include:
Month 1: Initial Technical Report providing an assessment of project goals, progress, status, as well as any issues and concerns. Phase I Kickoff Meeting.
Month 3: Interim Technical Report providing an update on the technical progress and status, as well as any issues and concerns.

The Draft Final Technical Report should additionally summarize/include proof-of-concept analysis and/or simulations; preliminary filter design; fabrication process; risk assessment and mitigation strategy; and commercialization plan outlining target markets, strategy, and potential DoW insertion opportunities.

PHASE II: The goal of Phase II is to demonstrate five or more functioning packaged filters that meet the technical metrics of the program using the design from Phase I. The phase consists of up to 36 months to fabricate the filters, and package functioning devices. During the base period, prototype devices will be fabricated and tested to validate performance against the program metrics. Deliverables for Phase II include quarterly technical and financial reports; a strategy report for packaging functioning devices; a final technical report listing the measured performance of the prototype filters against the metrics; and an updated commercialization plan with target markets, strategy, and potential DoW insertion opportunities. There will also be a kickoff meeting, quarterly meetings, and a closeout meeting.

PHASE III DUAL USE APPLICATIONS: Phase III refers to work that derives from, extends, or completes an effort made under prior SBIR funding agreements, but is funded by sources other than the SBIR program. Microwave filters are dual-use technology. Commercial applications include telecommunications, cognitive radios, software defined radios (SDR), and test equipment. Military applications include communications, signals intelligence, and electronic warfare. Under Phase III, the small business should focus on commercializing the filters and must obtain funding from either the private sector, a non-SBIR federal source, or both, to develop the prototype into a viable commercial product for sale in military or private sector markets.
