Gallium Arsenide

Point-to-Point Wireless Radios

Gallium arsenide (GaAs) technology has always been leading the implementation of the high frequency circuits in optical and wireless applications in commercial, military and space service markets. GaAs technology inherently has electronic properties superior to those of other mainstream Silicon based technologies, such as higher saturation current and wide band gap. These properties allows for the implementation of high frequency active and passive device with superior performance. With the recent explosive growth of high speed communications, GaAs technology continues to lead in those markets where performance is the driving force, be it high power, low noise or low jitter requirements.

RF Applications

GigPeak has been supplying advanced market dominating products using GaAs technology in optical, backhaul, instrumentation markets covering frequencies up to 86 GHz. These included driver amplifiers, Low Noise Ampliers (LNAs), Power Amplifiers (PAs), switches, attenuators and multi-function MMICs.
