1. A beamforming transmitter comprising:
a first digitally controlled power amplifier (DCPA);
a second DCPA;
a time shifting device coupled between the first DCPA and the second DCPA, the time shifting device comprising:
a phase selector device to receive a first signal and selectively output the first signal;
a coarse delay line coupled to the phase selector device and to provide a coarse delay; and
a digitally controlled edge interpolator (DCEI) coupled to the coarse delay device and configured to output a fine delay output based on the provided coarse delay.
