Engineered for harsh South American operating environments, military aircraft integration, and localized electronic defense programs.
Navigating environmental harshness, regulatory directives (ANATEL/DECEA), and mission-critical power constraints across South America’s primary aerospace ecosystem.
Brazil stands as the epicenter of South American aerospace engineering, anchored by global Tier-1 integrators such as Embraer (Empresa Brasileira de Aeronáutica) in São José dos Campos, along with specialized defense suppliers catering to the Brazilian Air Force (Força Aérea Brasileira - FAB), the Brazilian Navy (Marinha do Brasil), and the Brazilian Army (Exército Brasileiro). Avionics platforms operating across LATAM demand strictly qualified electrical power architectures able to handle aggressive thermal profiles, airborne bus transients, and intense electromagnetic interference (EMI).
As a veteran power supply manufacturer with over 35 years of dedicated design expertise, our engineering teams build custom, Commercial Off-The-Shelf (COTS), and Modified Off-The-Shelf (MOTS) power supplies specifically adapted to meet DO-160G and MIL-STD standards required by local Brazilian defense integrators and tier-one sub-contractors.
Deploying avionics power and RF countermeasure equipment in Brazil presents unique operational challenges that off-the-shelf industrial electronics fail to address:
Combining Solid-State Gallium Nitride (GaN) high-density topologies with MIL-STD power quality compliance for modern fixed-wing, rotary, and UAV platforms.
Our 700–6000MHz and ultra-wideband GaN Solid-State Power Amplifiers (SSPA) offer up to 80W–100W output power with market-leading power-added efficiency (PAE > 45%). Designed for active counter-UAV (Anti-FPV) and electronic attack suites, these modules feature rapid switching times, thermal protection, and low harmonic distortion.
Accepting 28 VDC nominal input (withstanding 16V to 50V transients) or 115 VAC / 400 Hz 3-phase power, our airborne AC-DC and DC-DC converters feature active Power Factor Correction (PFC > 0.98), tight multi-rail regulation, and internal hold-up capacitors for continuous operation during bus transfer transients.
Featuring 60g ultra-lightweight designs for tactical field forces and integrated air defense networks. Provides sub-2 second signal analysis across dual-mode detection protocols (such as DJI O4 remote control telemetry), facilitating early warning and precise automated jamming activation.

Adapting high-reliability power supply systems and RF defense payloads to critical domestic defense projects and infrastructure protection.
The Brazilian Army’s SISFRON program secures thousands of kilometers of land borders across Mato Grosso, Amazonas, and Paraná. Ground-based surveillance posts and tactical communications towers require rugged power supplies capable of operating continuously on remote solar hybrid systems or diesel generators. Our IP67-rated sealed AC-DC power supplies deliver clean DC voltage to perimeter radar sensors, electro-optical cameras, and passive 5km drone detection modules without maintenance interventions.
Naval vessel installations at the Itaguaí Naval Base require strict compliance with MIL-STD-1399 Section 300 power quality guidelines. Our zonal shipboard power management platforms integrate redundant N+1 backplane power converters and ruggedized rack-mount Uninterruptible Power Supplies (UPS). These systems isolate combat management command consoles and tactical sonar arrays from severe voltage spikes caused by heavy naval propulsion switching.
Exported worldwide, platforms like the KC-390 Millennium transport plane and A-29 Super Tucano light attack aircraft rely on weight-optimized avionics power conversion. Our conduction-cooled DC-DC converters step down high-voltage airborne buses to clean 28VDC/12VDC power for flight management systems, HUDs, and tactical radios—built to exceed DO-160G environmental and electrical test specs.
Unmanned Aerial Vehicle (UAV) intrusions pose growing threats to vital Brazilian assets such as the Itaipu Hydroelectric Dam, offshore oil platforms in the Santos Basin, and vast agricultural logistics hubs. Our 80W 700-6000MHz GaN RF modules and portable anti-drone passive detectors allow Brazilian security integrators to build directional jammer shields and automatic detection arrays capable of neutralizing commercial and custom FPV drones in real time.
Understanding procurement regulations, spectrum authority approvals, and tax optimization pathways for Brazilian importers and integrators.
Radio frequency modules exported to Brazil must comply with regulations set by the Agência Nacional de Telecomunicações (ANATEL). Our high-power RF GaN modules operate across tailored spectrum bands (433MHz, 1.2GHz, 5.8GHz, 6.5–7.2GHz) with controlled sideband emissions, facilitating smoother homologation for official defense and law enforcement deployments authorized by DECEA.
Navigating Brazil's import tax landscape (II, IPI, ICMS) via the Sistema Integrado de Comércio Exterior (Siscomex) requires accurate NCM cataloging. We supply precise technical data sheets, Certificate of Origin documents, and custom tariff classifications (under Ex-Tarifário regimes where applicable) to reduce landed customs duties for Brazilian defense importers.
As unauthorized drone flights threaten penitentiaries, international airports (such as Guarulhos and Galeão), and private agricultural estates, demand for modular, portable, low-power-consumption anti-drone modules is accelerating. Our ultra-light 60g passive detection modules respond to this local market trend directly.
Founded in 1987, AJ's Power Source Inc. (CAGE Code 0P327) is a Veteran-Owned Small Business specializing in high-reliability power conversion equipment. Unlike commercial distributors or catalog resellers, we perform total topology design, magnetics engineering, thermal simulation, and mechanical modeling in-house.
Direct technical and logistical answers for systems integrators, defense buyers, and aerospace engineers in South America.
Our avionics power conversion platforms integrate active input filtering, transient suppression diodes, and bulk hold-up capacitors specifically tuned to pass DO-160G Section 16 (Power Input) and Section 17 (Voltage Spike). They maintain steady DC output without resetting avionics computers during emergency bus transfers or engine starting voltage drops common in fixed-wing and rotorcraft fleets.
Every export shipment to Brazil includes a complete commercial invoice with detailed NCM/HS codes, detailed packing list, Certificate of Origin, ISO 9001 Certificate of Conformity, and technical data sheets required by Brazilian customs brokers to expedite clearance through Brazilian ports and airports.
Yes. Through our Modified Off-The-Shelf (MOTS) engineering program, we can adjust chassis dimensions, redesign mechanical mounting brackets, change output connector types (e.g., swapping standard terminals for MIL-DTL-38999 circular connectors), and adjust voltage rails to meet exact OEM physical space envelopes without incurring high clean-sheet NRE costs.
GaN HEMT transistors offer significantly higher electron mobility and power density compared to traditional silicon LDMOS. In tropical defense applications, GaN modules generate substantially less waste heat, operate efficiently at higher junction temperatures (+85°C baseplate), and allow jammer systems to deliver up to 100W RF output power from a compact, lightweight module ideal for vehicle or mast mounting.
Our sealed IP67 platforms utilize gasket-sealed CNC aluminum housings, pressure equalization vents (Gore valves) to prevent internal condensation caused by sudden temperature shifts, and full internal potting or conformal coating on all circuit boards. This ensures total protection against humidity, dust, and continuous rainfall in regions like northern Brazil.
Standard COTS units are evaluated and shipped within fast-track timeframes. Custom MOTS designs or customized GaN RF amplifier modules typically transition from initial CAD design freeze to verified prototype delivery within 6 to 10 weeks, backed by full engineering support throughout the integration cycle.
