A method of driving a mixer of a transmit chain within a wireless transmitter using a low third harmonic divider, LTHD, comprising: driving said mixer with a periodic signal being a difference in voltage or current between two signals (IP, IN) on two output conductors (136, 137) of said LTHD, wherein a period of the periodic signal includes a first portion, a second portion and a third portion, wherein the periodic signal has a first signal level during the first portion, wherein the periodic signal has a second signal level during the second portion, and wherein the periodic signal has a third signal level during the third portion, wherein the periodic signal is a first periodic signal, the second level is different from the first and the third level is different from the first and second levels, and wherein the first periodic signal is generated by frequency dividing a periodic input signal by a first value and thereby generating first signals, frequency dividing some of the first signals by a second value and thereby generating second signals, supplying the first and second signals to a plurality of logic gates so that the logic gates output a second periodic signal as a difference in voltage between two signals (IGP, IGN) on two output conductors (159, 160) of said logic gates, said second periodic signal having substantially no third harmonic component, and supplying the second periodic signal and the periodic input signal to a retiming circuit, characterized in that the retiming circuit uses the periodic input signal to retime the signal edges of the second periodic signal to improve the degree to which the switching of the second periodic signal occurs at the same time as the switching of the periodic input signal and outputting the first periodic signal, and in that the two signals (IP, IN) on the output conductors (136, 137) of said LTHD and the two signals (IGP, IGN) on the two output conductors (159, 160) of said logic gates have a duty cycle of one third and a phase shift with respect to each other of 180°. driving said mixer with a periodic signal being a difference in voltage or current between two signals (IP, IN) on two output conductors (136, 137) of said LTHD, wherein a period of the periodic signal includes a first portion, a second portion and a third portion, wherein the periodic signal has a first signal level during the first portion, wherein the periodic signal has a second signal level during the second portion, and wherein the periodic signal has a third signal level during the third portion, wherein the periodic signal is a first periodic signal, the second level is different from the first and the third level is different from the first and second levels, and wherein the first periodic signal is generated by frequency dividing a periodic input signal by a first value and thereby generating first signals, frequency dividing some of the first signals by a second value and thereby generating second signals, supplying the first and second signals to a plurality of logic gates so that the logic gates output a second periodic signal as a difference in voltage between two signals (IGP, IGN) on two output conductors (159, 160) of said logic gates, said second periodic signal having substantially no third harmonic component, and supplying the second periodic signal and the periodic input signal to a retiming circuit, characterized in that the retiming circuit uses the periodic input signal to retime the signal edges of the second periodic signal to improve the degree to which the switching of the second periodic signal occurs at the same time as the switching of the periodic input signal and outputting the first periodic signal, and in that the two signals (IP, IN) on the output conductors (136, 137) of said LTHD and the two signals (IGP, IGN) on the two output conductors (159, 160) of said logic gates have a duty cycle of one third and a phase shift with respect to each other of 180°.
