The design, implementation, measurements, and broadband calibration of a 16‐channel vector modulator (VM) module covering 1.5–2.4GHz band are presented in this study. Since the practical realisation of the VM suffers from the effects of non‐ideal characteristics, a broadband calibration technique is adopted which greatly improves the transmission of phase and amplitude accuracy of the VM over a wide frequency range. The measurement results of the calibrated VM are given to show the high calibration accuracy and efficiency of the proposed technique.
