摘要
该文阐述了一种高精度幅相调理机制(APMM),具有高可靠、高线性幅相特性及快速设计等优点。通过逐级联试,可使任意多通道模组的通道间相位差一致性≤±1°,任意功能单元间幅度一致性≤±1 dB,相位一致性≤±1.5°,任意功能单元的绝对延时精度≤±1.5 ps,多倍频相对带宽的幅度平坦度≤±1 dB。该调理机制可应用于任意电子系统、任意信道化设计、任意功能电路或芯片设计等。通过大量工程应用,并得以证实,该方案切实可靠地改善了目前各类射频系统或模块单元的幅相特性。
A high precision amplitude and phase modulation mechanism(APMM)with the advantages of high reliability,high linear amplitude and phase characteristics and fast design is described in this paper.Through the cascading test,the consistency of the phase difference between channels of any multi-channel module is±1°,the amplitude consistency between any functional units is less than±1 dB,the phase consistency is±1.5°,the absolute delay accuracy of any functional unit is±1.5 ps,and the amplitude flatness of multiple frequency relative bandwidths is±1 dB.This APMM can be applied to any electronic system,any channelized design,any functional circuit or chip design.Through a large number of engineering applications,it has been confirmed that the scheme has effectively and reliably improved the amplitude and phase characteristics of various RF systems or modules.
