I. ADI GaN Power Solutions

Traditional silicon-based power devices are limited by material properties, suffering from issues such as high switching losses, low operating frequencies, insufficient power density and poor high-temperature stability. As a result, they are ill-suited for high-voltage, high-frequency and high-efficiency applications such as high-efficiency power supply for data centres, electric vehicle power control, industrial frequency conversion and renewable energy inverters. ADI’s GaN power solutions are deeply optimised for the characteristics of wide-bandgap GaN HEMT devices, forming a comprehensive solution comprising ‘driver ICs + control ICs + power devices + system reference designs’. From low-level device matching to high-level system optimisation, this approach comprehensively enhances the efficiency, power density and stability of power systems.

1. Core Technical Advantages

- Ultra-low losses, extreme efficiency gains: By utilising the zero reverse recovery characteristic of GaN devices, switching and conduction losses are significantly reduced, enabling power systems to achieve peak conversion efficiencies of over 98 per cent. This represents a 3–8 per cent improvement in efficiency compared to traditional silicon-based solutions, effectively reducing equipment cooling demands and long-term energy costs.

- High-frequency miniaturisation, enhanced power density: Supports MHz-level high-frequency switching modes, significantly reducing the volume and weight of passive components such as transformers, inductors and capacitors within the power supply system. This facilitates compact and lightweight equipment design, with power density increased by over 50% compared to traditional solutions, making it ideally suited for high-end power supply applications with space constraints.

- Dedicated driver optimisation for more stable operation: ADI’s high-speed driver ICs, specifically optimised for GaN devices, precisely match the switching timing of GaN HEMTs. This effectively suppresses voltage spikes and oscillations during high-frequency switching, resolves issues such as crosstalk and false triggering in GaN devices operating at high frequencies, and enhances the system’s immunity to interference and long-term operational reliability.

- Wide temperature range and high reliability, suitable for demanding operating conditions: The solution supports operation across a wide temperature range, offering excellent high-temperature stability and overload resistance. It can withstand complex voltage fluctuations and thermal shocks in industrial and new energy applications, making it suitable for demanding industrial environments and high-temperature automotive settings.

- Simplified design, lower R&D barriers: It provides a standardised system architecture, mature reference designs and supporting debugging tools, optimises loop control logic, and is compatible with mainstream topologies, significantly reducing the design complexity, debugging time and R&D costs of GaN power supply systems.

2. Core Products and System Architecture

The ADI GaN power solution employs a fully integrated end-to-end design, comprising three core modules that form a complete closed-loop power system:

- Dedicated GaN driver IC: Custom-developed for enhancement-mode GaN HEMT devices, it features high-speed response, low latency and strong immunity to interference. It precisely controls the switching state of GaN devices, eliminating the risk of high-frequency oscillations and device breakdown, and is suitable for high-voltage, high-frequency, high-power applications.

- High-performance power control IC: Integrates high-precision loop control, peak current control, and overvoltage/overcurrent/over-temperature protection functions. It supports high-frequency PWM modulation and dynamic load regulation, enabling real-time adaptation to load fluctuations to ensure stable voltage and current output from the power supply system.

- Complementary power devices and modules: Paired with highly reliable GaN power transistors and utilising ADI’s system tuning technology, these solutions achieve deep optimisation between devices, control and drive circuits. Standardised power modules are also provided to facilitate rapid integration and deployment.

3. Core Application Scenarios

II. ADI GaN RF Solutions

In the RF and microwave fields, traditional GaAs and silicon-based RF devices suffer from issues such as low upper frequency limits, limited output power, insufficient linearity, and significant disadvantages in size, weight and power (SWaP). Consequently, they are unable to meet the demands of high-frequency, high-power and high-linearity applications such as 5G/6G millimetre-wave communications, aerospace and defence, high-precision test and measurement, and satellite communications. Leveraging advanced GaN semiconductor processes and comprehensive signal chain design capabilities, ADI’s GaN RF solutions cover an ultra-wide frequency range from kHz to 95 GHz. They provide a complete suite of solutions ranging from bare dies and discrete components to integrated modules and complete signal chains. With their advantages of high power, high linearity, wide bandwidth and high reliability, they serve as the core technological backbone for high-end RF systems.

1. Core Technical Advantages

- Ultra-wide bandwidth and ultra-high frequency coverage: Breaking through the frequency limitations of traditional RF devices, the operating frequency ranges from kHz to 95 GHz, making them perfectly suited for microwave and millimetre-wave high-frequency communication scenarios, whilst meeting both narrowband high-precision and wideband large-range signal processing requirements.

- High-power output with excellent power density: Leveraging the high-power handling characteristics of GaN material, it supports high-power RF output of up to nearly 1 kW per module. At equivalent power levels, the device’s volume and weight are significantly smaller than those of traditional solutions, substantially optimising the system’s SWaP metrics.

- High linearity, ensuring signal fidelity: Maintains excellent signal linearity even under high-power output conditions, effectively reducing signal distortion and spurious interference. This ensures high precision in RF signal transmission, amplification and transceiver operations, significantly enhancing signal quality in communication and measurement systems.

- High reliability and resistance to harsh environments: Possesses excellent resistance to high temperatures, radiation and interference, enabling long-term stable operation in demanding environments such as aviation, defence and outdoor base stations, whilst withstanding extreme temperature fluctuations and sustained high-frequency operational loads.

- High integration, simplifying the RF chain: Integrates multifunctional modules such as power amplification, signal modulation, gain control and signal detection. When paired with complementary full-chain components—including PLLs, mixers and detectors—it simplifies the RF front-end architecture, reduces the number of peripheral components and lowers system design complexity.
