US-based technology firm BANC3 has secured a defense contract to develop a wideband, non-blocking radio frequency (RF) switch matrix, a system aimed at bolstering the Pentagon’s electronic warfare and signals intelligence capabilities. The effort underscores the Department of Defense’s push to maintain spectrum dominance amid increasingly complex electromagnetic threats.
The centerpiece of the program is a 16×12 non-blocking RF switch matrix, enabling 16 inputs to connect simultaneously to 12 outputs without interference. Covering frequencies from 6 to 18 gigahertz, with scalability up to 40 gigahertz, the system will be packaged in a rugged 6U VPX form factor. This architecture is widely used in military and aerospace electronics where size, weight, and power efficiency are critical factors.
Non-blocking switch matrices are essential for spectrum surveillance and electronic warfare, allowing multiple antennas to operate seamlessly with multiple receivers. Such flexibility has become vital as adversaries increasingly adopt frequency-agile systems, particularly within the X-band (8–12 GHz) and Ku-band (12–18 GHz).
BANC3’s upcoming solution is designed for adaptability and potential upgrades across US platforms. Candidate systems include the Navy’s P-8 Poseidon patrol aircraft, the MQ-4C Triton unmanned aerial system, and Tactical Air Control Party missions within Air Force Special Warfare. The technology also aligns with the Department of Defense’s Joint All-Domain Command and Control (JADC2) initiative, which seeks to unify communications and data sharing across all branches.
Though the company has not disclosed contract value or schedule, the initiative reflects continued Pentagon investments in electromagnetic spectrum dominance. Beyond defense, wideband RF switching systems may eventually find applications in regulatory spectrum monitoring and commercial RF testing markets.
