Technologies Empowering RF Signal Chain R&D for High-Power Microwave Systems

ABSTRACT: As DoD interest in high-power microwaves (HPM) grows, there is significant emphasis being placed on optimizing the underlying RF signal chain. The RF portion generates the waveform, applies modulation if required, amplifies while preserving fidelity, and validates key parameters that determines how effectively microwave energy engages with a target. This article outlines commercial off-the-shelf (COTS) solutions, such as signal generators, noise sources, amplifiers, and power measurement instrumentation, that support and accelerate the R&D of the HPM RF signal chain.
