Defense electronics is driving GaN based RF semiconductor market

ABI Research states in its latest release "Although spending on RF power semiconductors in wireless infrastructure markets has continued to stagnate, other markets - notably the military - are seeing increased activity. Also, according to a new study from ABI Research, Gallium Nitride - long seen as a promising new "material of choice" for RF power semiconductors - is continuing to gain some market traction."

"Gallium Nitride (GaN) increased its market share in 2010," notes ABI Research director Lance Wilson. "It is expected to do the same in 2011. Although its adoption hasn't been as rapid as originally expected, it is nonetheless forecast to be a significant force by 2016."

As per ABI, GaN bridges the gap between two older technologies, exhibiting the high-frequency performance of Gallium Arsenide combined with the power handling capabilities of Silicon LDMOS. It is now a mainstream technology which has achieved measurable market share and in future will capture a substantial part of the market.

Other than wireless infrastructure, the vertical market showing the strongest uptick in the RF power semiconductor business has been the military, which Wilson describes as being now "a very significant market." While the producers of these devices are located in the major industrialized countries, the military market is now so global that equipment buyers can come from anywhere.
