Figure 3-35: I/Q modulation
I/Q modulation is performed by means of the built-in quadrature modulator. The RF
signal is divided into two orthogonal I and Q components (in phase and quadrature
phase). Amplitude and phase are controlled in each path by the I and Q modulation
signal. By adding the two components an RF output signal is generated that can be
controlled in amplitude and phase.
