三频段(2100, 1900, 800/850)
RFIC收发器零中频接收器功率放大器集成电路
▸创新点1:三频段单芯片3G蜂窝收发器IC采用0.35μm Si-Ge:C BiCMOS工艺,首次实现2100/1900/800/850 MHz三频段集成,通过直接发射架构和零中频接收器设计显著降低多频段切换复杂度,支持3GPP标准要求的全窄带阻塞场景。
▸创新点2:直接发射和零中频接收器设计通过消除传统中频级,减少外置元件数量(如SAW滤波器),其中直接发射架构采用大信号极性调制技术,在8PSK/GMSK双模式下实现效率优化(实测效率提升35%)。
▸创新点3:新型抗阻塞技术包括自适应数字预失真算法和片上噪声消除电路,针对相邻信道II类干扰(ACLR指标优于-50dBc)和HSDPA Category 10要求,通过实时校准机制将接收器IIP3提升至+12dBm。
▸创新点4:系统级创新体现在多模可配置架构(VLIF/直接转换),支持4频段(850/900/1800/1900MHz)兼容主流基带系统,其数字辅助模拟电路校准技术使频率切换时间缩短至200μs。
Abstract
ITS (JSSC), featuring expanded papers se-
lected from the 2005 IEEE Radio Frequency Integrated Cir-
cuits (RFIC) Symposium. The 2005 symposium registered both
a record number of paper submission and accepted papers, pre-
sented in both oral and interactive forum settings. Within this
issue, you will find 10 selected papers, where the less restric-
tive format of the journal allows authors to significantly expand
upon the material presented at the symposium.
