中文摘要:
      提出描述了数字矢量调制器的设计方法、实现过程及试验结果。该数字矢量调制器采用数字与模拟相结合、混合集成工艺技术实现,其调试简单,控制电压与电压传输系数成线性关系,一致性好。在VHF频段内,衰减量变化30 dB时,其相位误差变化小于±1.5°,I路与Q路的正交性小于±2°。
英文摘要:
      The design method, implementation and testing results of a digital vector modulator are described in this paper. The proposed digital vector modulator is combined the digital technology and analog technology, implemented by the microwave hybrid integrated technology, and has the features of easy to adjust, good linearity with the control voltage and voltage transmission coefficient. The phase error change is less than ±1.5° and I/Q orthogonality is less than ±2° when the attenuation decrement change is 30 dB in VHF frequency range.
