COMPACT WIDEBAND TUNABLE FILTERS

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)[1] 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.
