摘要

提出了一种用于三扇区无线小区中功率放大器负载平衡的低损耗3/ 1倍/3路相位合成器。基于充气同轴双环结构，该设计结合了极低的插入损耗和紧凑的物理外形。以个人通信业务(PCS) 1.91 GHz ~ 1.99 GHz发射频段为例，通过仿真研究了该概念。测量结果验证了预测的极低插入损耗为0.05 dB，而回波损耗和端口隔离均优于25 dB。

3-way low loss phase combiner for power amplifier sharing in 3-sector cellular networks

A low loss 3/spl times/3-way phase combiner for power amplifier load balancing in 3-sector wireless network cells is presented. Based on an air-filled coaxial double ring structure this design combines very low insertion loss with compact physical profile. Exemplary, the concept is studied for the PCS (personal communication service) transmit band from 1.91 GHz to 1.99 GHz by simulations. Measurements validate the predicted very low insertion loss of 0.05 dB, while return loss and port isolation are both better than 25 dB.
