Silicon germanium (SiGe) ICs that eliminate the need for multiple components in 900, 1800 and 1900 MHz front-end applications
SiGe Front-end RFICs CommQuest, an IBM company Encinitas, CA The advantages of the silicon germanium (SiGe) semiconductor process have provided a price-to-performance ratio not available thus far from existing component technologies. SiGe power amplifiers achieve better than 55 percent power-added efficiency while today’s GaAs-based products offer no more than...
