Conexantt 查询号183科胜讯系统公司开发了一种新的单片射频收发机CX74017,使多频GSM手机的设计进一步合理化。通过淘汰昂贵的中频转换过程,CX74017直接转换收发机使制造移动手机所需要的外部元件的数量减少了三分之一,大大降低了新一代GSM手机的成本、体积和功率要求。由于
Conexant Inquiries 183 Conexant Systems has developed the CX74017, a new monolithic RF transceiver that further rationalizes the design of multi-band GSM handsets. The CX74017 direct conversion transceiver reduced the number of external components needed to make mobile handsets by one-third by eliminating expensive intermediate-frequency conversion processes, dramatically reducing the cost, size and power requirements of next-generation GSM handsets. due to
