Abstract
A phased array transmitter is disclosed comprising a vector modulator, a true time delay block coupled to the vector modulator, a local oscillator phase shifter and RF-converter block coupled to the true time delay block, and an antenna. The vector modulator applies vector modulation to a baseband signal and provides an intermediate frequency signal to the true time delay block. The true time delay block applies a true time delay to the intermediate frequency signal and provides a delayed intermediate frequency signal to the local oscillator phase shifter and RF-converter block. The local oscillator phase shifter and RF-converter block multiplies the delayed intermediate frequency signal by a local oscillator signal and applies a phase shift to the delayed intermediate frequency signal to provide a radio frequency signal to the antenna for onwards transmission.
