By implementing the sampling process at an AC ground node, rather than at a signal side, and adding a gated transistor ( 610 and 620 ) in the signal path, the present invention reduces the interdependency between gain and linearity in a switched capacitor mixer circuit, supplies higher power without sacrificing area and simplifies the implementation of the RF switch. Charge boosting circuitry ( 630 ) allows a reduction in the effective size of a series switch ( 610 and 620 ) that follows a transconductance element ( 115 ).
