| Abstract: | In order to improve the technical index of vector modulator and realize a better performance in the usage of RF interference cancellation, the technical scheme of digital control vector modulator is proposed in this paper. The stable and high precision step control can be realized by using this proposed digital control vector. The testing results show that the developed vector modulator module has realized the step precision of less than 0.03 dB which has satisfied the system requirement. |
