The electrical signal is split, to be directed on a phase path (28) and an amplitude path (30).

The aspects of the electromagnetic wave to be processed may be amplitude and phase, where the comparison may be along the phase path and the adjustment along an analog portion of the amplitude path.

Provided is a transmitter circuit capable of adjusting the difference between the amounts of signal delay in the amplitude path and the phase path while consuming low power.

This signal (FB) is fed back to a delay adjustment unit (12) and used to calculate and adjust the difference between the amounts of signal delay in the amplitude path and the phase path.
