It worked well enough for the threat environment of that era.\u003C\u002Fp>\n\u003Cp>That threat environment no longer exists.\u003C\u002Fp>\n\u003Cp>The drones that now threaten airports, military positions, energy infrastructure, and crowded stadiums are not the same devices that motivated the first generation of counter-UAS deployments. They operate across a wider frequency range, use frequency-hopping protocols that defeat narrowband jamming, and are manufactured at price points that make mass deployment trivially accessible. Stopping them requires a fundamentally different RF performance profile -which is why GaN has become not just the preferred option, but the de facto standard for credible counter-drone jamming systems.\u003C\u002Fp>\n\u003Chr\u002F>\n\u003Ch2>What Changed: The Post-2022 Threat Specification\u003C\u002Fh2>\n\u003Cp>Three categories of drones emerged from the Ukraine conflict with direct implications for C-UAS technology requirements.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Commercial off-the-shelf (COTS) reconnaissance drones\u003C\u002Fstrong> -DJI Mavic and similar platforms -operate on standard consumer frequencies: 2.4GHz and 5.8GHz for video links, GPS for navigation. These are the same drones interrupting NFL playoffs and threatening airport approaches. Their frequency profile is well-understood, but their availability is essentially unlimited.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>FPV kamikaze drones\u003C\u002Fstrong> -racing quadcopters repurposed as loitering munitions -use analog video transmission on non-standard frequencies, often outside the 2.4\u002F5.8GHz bands that first-generation jamming systems were built around. Narrowband systems calibrated for DJI simply don't touch these platforms.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>GNSS-independent and frequency-hopping platforms\u003C\u002Fstrong> represent the emerging edge. Modern drone firmware increasingly supports frequency-hopping spread spectrum (FHSS), which cycles through dozens of sub-channels to evade detection and jamming. Defeating FHSS requires high output power sustained continuously across the full spread -not bursts on a single frequency.\u003C\u002Fp>\n\u003Cp>\u003Cimg src=\"https:\u002F\u002Fpub-5703319218b24540891c4df11d304f71.r2.dev\u002Farticles\u002Fimages\u002Fhotspot-03-spec-table.png\" alt=\"Pre vs Post-2022 Counter-Drone Specifications\" style=\"max-width:100%;\"\u002F>\u003C\u002Fp>\n\u003Cp>The procurement specification that resulted from these observations is now consistent across US, UK, EU, and Gulf state C-UAS documents: \u003Cstrong>full-band coverage from 380MHz to 5.8GHz, continuous output at 50W to 100W minimum, operating range from -40°C to +60°C.\u003C\u002Fstrong> LDMOS technology cannot meet this specification. GaN can.\u003C\u002Fp>\n\u003Chr\u002F>\n\u003Ch2>The Physics of Why GaN Wins\u003C\u002Fh2>\n\u003Cp>The performance gap between GaN and LDMOS is rooted in semiconductor physics, not marketing.\u003C\u002Fp>\n\u003Cp>GaN (Gallium Nitride) is a wide-bandgap semiconductor. Its electron mobility is substantially higher than silicon-based LDMOS, which means it can switch faster, sustain higher voltages, and maintain efficiency at higher frequencies. The practical outcomes of this at the component level are significant:\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Power density.\u003C\u002Fstrong> GaN delivers 4-6 watts per millimeter of gate width, compared to 0.5-1.5 W\u002Fmm for LDMOS. In practice, this means a GaN module producing 50W output can be physically 80% smaller than an equivalent LDMOS design -a critical advantage for vehicle-mounted and portable C-UAS systems where space and weight are constraints.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Efficiency across frequency.\u003C\u002Fstrong> LDMOS performs well at frequencies below 2.7GHz but degrades sharply above that. GaN maintains high efficiency across the 100MHz-6GHz range. For a counter-drone system that needs to simultaneously cover 433MHz control links, 2.4GHz and 5.8GHz consumer bands, and GPS frequencies around 1.5GHz, this matters: a single GaN amplifier stage can cover the entire relevant spectrum. An LDMOS-based design requires multiple discrete amplifiers stacked together -adding cost, complexity, and points of failure.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Thermal performance.\u003C\u002Fstrong> GaN's higher power-added efficiency (55-65% PAE versus 45-55% for LDMOS) means less waste heat per watt of output. For counter-drone applications requiring continuous 24\u002F7 operation -airport perimeter security, border installations, fixed critical infrastructure -thermal management directly determines whether a system can run reliably without cooling infrastructure. GaN modules operating at 50W-100W output can sustain 24\u002F7 operation in ambient temperatures up to 55°C without active liquid cooling.\u003C\u002Fp>\n\u003Cp>\u003Cimg src=\"https:\u002F\u002Fpub-5703319218b24540891c4df11d304f71.r2.dev\u002Farticles\u002Fimages\u002Fhotspot-03-comparison.png\" alt=\"GaN vs LDMOS: Power Density Comparison\" style=\"max-width:100%;\"\u002F>\u003C\u002Fp>\n\u003Cp style=\"text-align:center;color:#666;font-size:0.9em;\">\u003Cem>GaN delivers equivalent RF output in a fraction of the physical footprint, enabling compact C-UAS deployment formats.\u003C\u002Fem>\u003C\u002Fp>\n\u003Chr\u002F>\n\u003Ch2>Real-World Validation: From Ukraine to Super Bowl LIX\u003C\u002Fh2>\n\u003Cp>The pivot toward GaN in C-UAS procurement is not theoretical -it is traceable in specific hardware deployments.\u003C\u002Fp>\n\u003Cp>The Epirus Leonidas high-power microwave (HPM) system, now part of the US Department of Defense's counter-UAS portfolio, is built entirely on solid-state GaN semiconductor technology.

GaN RF technology is embedded in the jamming subsystems across this program.\u003C\u002Fp>\n\u003Cp>RFHIC, one of the leading commercial GaN amplifier manufacturers, publishes a specific counter-drone product line covering 100MHz-6GHz at 100W CW output -explicitly targeting the C-UAS frequency specification. Multiple other commercial C-UAS manufacturers -including those supplying to the Super Bowl LIX security deployment, which intercepted over 70 unauthorized drones -have standardized on GaN power amplifier modules for their jamming subsystems.\u003C\u002Fp>\n\u003Cp>The pattern is consistent: wherever the post-2022 C-UAS specification is being implemented seriously, GaN is the RF power technology underneath it.\u003C\u002Fp>\n\u003Chr\u002F>\n\u003Ch2>What This Means for System Integrators\u003C\u002Fh2>\n\u003Cp>The practical implication for anyone designing or procuring counter-drone systems is that LDMOS-based jamming subsystems are no longer a credible option for anything beyond the most limited, fixed-frequency threat environments.

Not all commercial GaN modules do this -many are designed for cellular infrastructure or radar applications with narrower frequency coverage or different linearity requirements. Counter-drone RF modules need wideband coverage optimized for continuous jamming output rather than communications linearity.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Integration.\u003C\u002Fstrong> System integrators sourcing jamming subsystems are increasingly looking for modular GaN RF components rather than complete proprietary jammer units -the modular approach allows integration into existing detection architectures without a full system replacement.
