摘要

除了话音通信外，宽带CDMA还被设想用于传输高比特率数据和视频信息。IMT2000标准采用了2.11至2.17 GHz频段来提供这项服务，这对设计提出了挑战，即比PCS (1.8-1.99 GHz)更高的工作频段和更宽的信号调制带宽。本文介绍了一种以IMT2000频段W- cdma信号为特征的60 W单端和120 W推挽RF LDMOS器件的实验结果。

Application of RF LDMOS power transistors for 2.2 GHz wideband-CDMA

Wideband CDMA was conceived to carry high bit rate data and video information in addition to voice traffic. The IMT2000 standard has adopted the 2.11 to 2.17 GHz band for this service, posing the design challenge of a higher operating frequency band than the PCS (1.8-1.99 GHz) and wider modulation bandwidth for the signals. This paper describes the results for a 60 W single-ended and a 120 W push-pull RF LDMOS device characterized with W-CDMA signals in the IMT2000 frequency band.
