Abstract

In recent years, for the realization of the low-cost and multi-band AP AA (Active Phased Array Antenna) system, broadband and highly accurate vector-sum phase shifter has attracted the attention. To realize such a vector-sum phase shifter, one of the difficulty arises from the trade-off between a bandwidth and an insertion loss of the PPF (Poly Phase Filter) which is deployed at the first stage inside the phase shifter and generates quadrature signals from a differential signal. In order to ease the trade-off of PPF, we propose the PPF using inductor and capacitor (LC-type) power splitter implemented in front of it. Simulation results with the proposed technique show the improvement of 2.7dB in the insertion loss, without degradation of the bandwidth. As a proof of concept, vector-sum phase shifter with the proposed PPF technique was fabricated using 0.18um SiGe BiCMOS process. Measurement results showed the 3dB gain bandwidth of 64% at X-band and the RMS phase error of less than 2.1°. This broadband and highly accurate results show that the proposed PPF technique is effective to realize multi-band AP AA system in the near future.

采用lc型功率分配器的宽带高精度x波段矢量和移相器
近年来,为了实现低成本、多频段的有源相控阵天线系统,宽带、高精度矢量和移相器引起了人们的关注。为了实现这样一个矢量和移相器,其中一个困难来自于带宽和PPF(多相滤波器)的插入损耗之间的权衡,该滤波器部署在移相器内部的第一级,并从差分信号产生正交信号。为了减轻PPF的权衡,我们提出了在PPF前面实现电感和电容(lc型)功率分配器的PPF。仿真结果表明,在不降低带宽的情况下,该技术的插入损耗提高了2.7dB。作为概念验证,采用0.18um SiGe BiCMOS工艺制作了具有PPF技术的矢量和移相器。测量结果表明,x波段3dB增益带宽为64%,均方根相位误差小于2.1°。这一宽带和高精度的结果表明,所提出的PPF技术在不久的将来是实现多频段AP AA系统的有效方法。
