A dynamically matched mixer system (200) for use in a direct conversion
radio frequency (RF) receiver includes a frequency generator (201, 203,
205) that includes plurality of dividers (407) for providing differential
local oscillator reference sources (F.sub.LO+ and F.sub.LO-) and
mitigation frequency reference sources (F1 and F2) from reference
oscillator (205). A mixer (209) mixes the differential local oscillator
reference sources (F.sub.LO+ and F.sub.LO-) and the mitigation frequency
reference sources (F1 and F2) while dynamic matching units (211, 213) are
used for receiving the mitigation frequency reference sources and
matching switching parameters of differential input signals (I.sub.RF+
and I.sub.RF-) and differential baseband output signals (I.sub.BB+ and
I.sub.BB-). The frequencies of the mitigation frequency reference sources
(F1 and F2) are selected so as to establish a non-integer relationship to
the reference oscillator (201) for mitigating the occurrence of
interference with F.sub.LO+ and F.sub.LO-.
