Metamag has introduced its Gyromagnetic Non-Linear Transmission Line (GNLTL) technology, a solid-state solution designed to generate extremely high-power pulsed microwave signals for advanced electronic warfare applications. The technology is positioned to support next-generation Counter-Unmanned Aircraft Systems (CUAS) and other spectrum-dominance missions where disabling electronics at range is critical.
GNLTLs are capable of producing microwave pulses with exceptionally high instantaneous power, reaching tens of megawatts. When integrated into a high-power microwave (HPM) system, these pulses can disrupt or permanently damage electronic systems, offering a non-kinetic option for countering modern electronic threats. Metamag notes that the technology is particularly well-suited for CUAS scenarios, where rapid, repeatable, and scalable electronic effects are required.

The company currently offers three GNLTL models, differentiated by operating frequency. The Low Band system operates at 800 MHz and delivers the highest output power, while the Mid Band and High Band models operate at 2.2 GHz and 3.5 GHz, respectively. When driven by a 50 kV input pulse, each model generates high-power RF output at its designated frequency. Metamag is also continuing the development of GNLTLs at higher frequencies, including X-band, to expand operational flexibility.

GNLTLs can be combined with a high-voltage pulser and a high-power microwave antenna to form a complete HPM subsystem. Such systems can be integrated with target tracking and fire-control architectures, enabling deployment across a wide range of defense platforms. Metamag emphasizes that the technology is platform-agnostic and suitable for land-, sea-, air-, and space-based systems.
Built using rugged solid-state materials, the GNLTLs are designed for long-term reliability and consistent performance. The company reports proven pulse-to-pulse repeatability, with systems tested over millions of pulses at high repetition rates. Tunable frequency and power levels allow operators to tailor electronic effects to specific mission requirements.
Metamag's GNLTLs are designed, fabricated, and assembled entirely in the United States, ensuring domestic control over manufacturing and supply chains. With the introduction of this technology, Metamag aims to strengthen the role of solid-state high-power microwave systems in future electronic warfare and counter-drone operations.
