摘要
基于LTCC技术设计了一款双通道应用的开关、驱动和低噪放一体化模块,利用HFSS对无源器件电感进行仿真,将电感嵌入LTCC基板中,不仅提高了模块的集成度,同时也降低了成本。在1.8~2.1 GHz频段内,ANT-RX通道增益达到23.8 dB,输入驻波比小于1.49,输出驻波比小于1.33,通道隔离大于44 dB,噪声系数小于1.21 dB（含评估板单端损耗约为0.15 dB）;ANT-TX通道插入损耗小于0.42 dB（含评估版损耗约0.3 dB）,输入输出驻波比均小于1.1。
Based on LTCC technology, a drived integrated switch-LNA module is designed in the paper. Inductance embeded in multi-layered LTCC substrate is simulated by using commercial 3D electromagnetic field analysis software HFSS. It can not only improve the integration,but also reduce the cost. Gain of this LNA module is 23.8 dB from 1.8 to 2.1 GHz. For ANT-RX chan- nel, input and output VSWR are less than 1.49 and 1.33, respectively, channel isolation is more than 44 dB, the noise figure is 1.21 dB（contained 0.15 dB in loss of one port of evaluation board）. For ANT-TX channel, insert loss is 0. 42 dB （contained 0.3 dB of evaluation board loss）, input and output VSWR are all less than 1.1.
