Up-conversion mixer having a reduced third order harmonic
An up-conversion mixer includes a mixer cell having at least one output node configured to generate an output. The up-conversion mixer further includes a first cascaded transconductance input stage coupled to the mixer cell, the first cascaded transconductance input stage configured to receive an input signal and to reduce a third order harmonic of the output. The up-conversion mixer further includes a second cascaded transconductance input stage coupled to the mixer cell, the second cascaded transconductance input stage configured to receive the input signal and to reduce a third order harmonic of the output.
