Military Spending and GaN Adoption Driving RF Power Semiconductor Markets, Says ABI Research
10:48 GMT, January 26, 2011 SCOTTSDALE, Ariz. | Although spending on RF power semicon
ductors in wireless infrastructure markets has continued to stagnate, other markets – notably the military – are seeing increase
d 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.
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
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. While the producers of these devices are locate
d in the major industrialized countries, the military market is now so global that equipment buyers can come from anywhere.
“RF Power Semiconductors” examines RF power semiconductor devices that have power outputs of greater than 5 watts and operate at frequencies of up to 3.8 GHz, which represent the bulk of applications in use today.
