Semiconductors Simplify Direct-Conversion Design
Direct-conversion architectures enable the broadband radios needed to support multimode, multiple standards in third-generation (3G) and fourth-generation (4G) wireless networks. The capability of handling signals from 400 MHz to 4 GHz across the globe has pushed infrastructure and mobile-device developers to seek new levels of performance for the components in those systems. Fortunately, improved silicon germanium (SiGe) and CMOS...
