A method for controlling local oscillator (LO) feed-through in a direct
transmitter includes detecting a signal level corresponding to LO
feed-through in a radio frequency (RF) signal that is output by a direct
transmitter. Responsive to detecting the signal level corresponding to LO
feed-through, DC offset levels are modified for an in-phase (I) signal
and/or a quadrature-phase (Q) signal in the direct transmitter.
