Phase-Coherent Signal Generation Based on Single-Sideband Time-Modulator

A method for achieving an 8-channel phase-coherent signal source through time modulation is proposed. Utilizing a power divider to split the signal into multiple paths and designing the control timing design of the single-sideband time modulation (SSBTM) module to achieve phase control of the radio frequency (RF) signals, thereby obtaining a phase-coherent signal source. The phase differences of two channel is measured with the root means square errors (RMSE) of 0.30° and maximum error of 0.68° from 300MHz to 3GHz.
