High Thermal Performance Gallium Nitride Power Amplifier and Transmit/Receive Module Packaging
The development of Wide Bandgap Semiconductors such as GaN has enabled tremendous improvements in power amplifier performance such as operational frequency and output power. These device improvements have in turn enabled performance and capability improvements in the end applications such as EW systems and radar T/R modules. The advances in device technology have not come without their own set of limitations which must yet be overcome. One issue that plagues equipment designers is the need for improved thermal efficiency which is exacerbated by the continuing requirement for smaller equipment footprints combined with increased functionality. While the development of ceramic multi-layer technologies has allowed smaller footprints to be realized through embedded circuitry and denser packaging, the thermal conductivity of such packages has not kept pace with the device technology itself. With the increased power densities expected from newer device technologies, an improved and advanced multi-layer packaging technology is being developed which takes into account the substrate materials and processing, the heat spreader material and attachment method, the final package into which the modules are mounted, newer devices and attachment materials, and the manufacturing and assembly processes in order to yield a high performance, thermally efficient, cost effective packaging solution.
