6 × 6 MM QUAD-BAND RF TRANSMIT MODULES FOR HIGH EFFICIENCY EDGE OPERATION

摘要

In today's fast paced mobile handset market, design houses and manufacturers are challenged to meet a variety of targets to satisfy network provider's high expectations in cellular and multimedia phones. Design cycle time, performance, feature requirements, form factor, quality and cost targets remain dominant selection criteria for mobile phone designers.rnNext generation mobile multimedia applications (combining GSM/GPRS/EDGE/ WCDMA/WLAN/GPS in one phone, for example) put even more stringent requirements on the hardware architecture. Partitioning of the baseband and RF components are critical handset design decisions with respect to functionality, performance, integration level, size and cost.
