US Navy relies on directed energy (DE) weapons, such as High-Power Microwave (HPM) sources, to disrupt, damage, or destroy foe electronic equipment at a standoff distance while minimizing collateral damage. Friendly and blue force mission critical electronic systems, such as radar, communications, navigation, sensors, guidance, fire control, etc. are vulnerable to both friendly and enemy DE weapons. US Navy requires test capability to generate arbitrary HPM signals in order to both improve the effectiveness of its DE weapons against specific enemy targets and to reduce the susceptibility of friendly systems to foe DE attacks. We propose to address the Navy requirement for a flexible and efficient HPM test capability by leveraging our prior Navy-funded work and innovative concepts to develop a solid-state High-Power Radio-Frequency (HPRF) source based on a planar and modular Non-linear Transmission Line (NLTL) RF oscillator triggered through a ultra-fast stacked MOSFET high-voltage switch. The wavelet synthesis approach will be utilized to generate essentially arbitrarily shaped waveforms by adjusting relative delays and amplitudes among array elements.

Metamagnetics proposes the research and development of a compact, reliable, cost-effective and reconfigurable pulsed-voltage source based on drift step recovery diodes (DSRD) for high-power microwave generation applications. The output parameters of the pulsed-voltage source determine the efficiency and agility in the use of electromagnetic spectrum and influence, among other factors, the operating frequency, bandwidth, and frequency dispersion of the HPM output of the system. The specific technology used to implement the pulsed-voltage source further affects the overall system size and weight. It is clear that in order to realize compact HPM systems that deliver a favorable combination of performance, size, weight, and power, the fundamental challenge of generating high-voltage pulses to drive these systems has to be addressed. Described herein, is a research and development program aimed at addressing the specific challenges of excitation of HPM sources through a combination theoretical and experimental effort aimed at advancing the state-of-the-art in Navy"s HPM capabilities.

During the course of this proposed Phase II program, Metamagnetics Inc. will continue the efforts toward development of a compact solid-state High Power Radio-Frequency (HPRF) source by building upon the results obtained from our Phase I effort, whereby a proof-of-feasibility demonstration of an innovative c (NLTL) for the generation of HPRF signals was achieved.This proposed system will be capable of generating arbitrary waveforms from the VHF to S-band band and delivering a minimum RF power of 10 MW at a rep-rate of 1 kHz. The development of such a system addresses the Navys requirement for a flexible and efficient high-power microwave (HPM) test capability system.In evaluating system performance, Metamagnetics Inc. will coordinate with Government and Industry partners. These synergistic activities will enable the development of a complete HPRF system with each performer contributing their unique expertise and capabilities.

Monolithic Microwave Integrated Circuits realized on GaAs, GaN, InP, SiGe, and to a lesser extent Si are integral components of many deployed NAVY detect, control, and engagement systems due to their broad bandwidth, fast-response time, and small size (10 W).

Increasing global RF electromagnetic (EM) activity related to commercial, scientific, and military systems, threatens the integrity of satellite communication links and has resulted in an environment cluttered with RF signals, particularly in the UHF-band. This is causing two major problems: 1) interference (due to co-site and jamming); and 2) increase in the EM noise floor. These effects can cause loss of information, reduce effective data transmission rate, and compromise system operability.Metamagnetics proposes the development of analog, low-cost, passive component solutions based on the unique non-linear properties of ferrite materials to address incoming interference threats and promote low-background-noise transmission of outgoing signals. Incoming signals will be safely received using a UHF-band frequency-selective limiter (FSL) and signal-to-noise enhancer (SNE). These combined technologies provide selective attenuation of co-site interference and jamming threats (via FSL), in addition to reducing the background EM noise floor (via SNE), while simultaneously allowing for friendly signals to pass unaffected. Outgoing signals will pass through a UHF-band SNE, before transmission, to purify the signal by attenuating unwanted spectral content.The proposed technology meets urgent Navy needs for mitigation of co-site interference and jamming threats, and addresses the rising background EM noise level, on increasingly-electromagnetically-cluttered satellite communication links.
