Gallium Nitride Integration: Breaking Down Technical Barriers Quickly

An integrated circuit made using GaN-on-Si substrates has been in production for over five years. The ultimate goal is to achieve a single component IC that merely requires a simple digital input from a microcontroller and produces a power output that drives a load efficiently, reliably under all conditions, in the smallest space possible, and economically. Discrete power transistors, whether silicon-based or GaN-on-Si, are entering their final chapter. Integrated GaN-on-Si can offer higher performance in a smaller footprint with significantly reduced engineering required.

Qualifying and Quantifying GaN Devices for Power Applications

It’s okay to start using gallium-nitride (GaN) devices in your new designs. GaN transistors have become extremely popular in recent years. These wide-bandgap devices have been replacing LDMOS transistors in many power applications. For example, GaN devices are broadly being adopted for new RF power amplifiers used in cellular base stations, radar, satellites, and other high-frequency applications. In general, their ability to endure higher voltages and operate at frequencies well into the millimeter-wave (mmWave) range have them replacing traditional RF power transistors in most amplifier configurations.

GaN in Space

This article discussed an oft forgotten or little-noticed part of the spacecraft enabling travel into outer space---power management in the space vehicle. Wide bandgap semiconductors like gallium nitride (GaN), silicon carbide (SiC), as well as diamond, are looking to be the most promising materials for future electronic components since the discovery of silicon. These technologies, depending upon their design, offer huge advantages in terms of power capability (DC and microwave), radiation insensitivity, high temperature and high frequency operation, optical properties and even low noise capability. Therefore, wide bandgap components are strategically important for the development of next generation space-borne systems. eGaN devices are quickly gaining momentum in the space industry and we will see many more applications for them by NASA and commercial contractors in future programs like Artemis and other programs in countries around the globe pursuing efforts into Space.

氮化鎵正面攻擊矽功率MOSFET元件

目前的氮化鎵場效應電晶體在尺寸及性能方面以飛快的速度發展,而目前為業界樹立基準的氮化鎵元件的性能還可以提升多300倍。

最早採用氮化鎵元件的應用是利用氮化鎵的超快速開關速度,例如面向全自動駕駛車輛和無人機的雷射雷達系統、機械人,以及4G/LTE基站。氮化鎵元件的產量一直在增加,而其價格跟開關速度更慢、尺寸更大型和日益陳舊的MOSFET元件相約。因此,目前正是氮化鎵元件正面攻擊MOSET的時候!。

Thermal design for a high density GaN-based power stage

eGaN FETs and ICs enable very high-density power converter design, owing to their compact size, ultra-fast switching, and low on-resistance. The limiting factor for output power in most high-density converters is junction temperature, which prompts the need for more effective thermal design. The chip-scale packaging of eGaN FETs and ICs offer six-sided cooling, with effective heat extraction from the bottom, top, and sides of the die. This article presents a high-performance thermal solution to extend the output current capability of eGaN-based converters.
