ABSTRACT:
A system or method for a circuit network that receives an RF signal, and where a plurality of switching transistors receive an RF signal output by the circuit network and perform mixing with a local oscillation (LO) signal received on a LO input. An active bias circuit performs active bias of the plurality of switching transistors in a feedback loop provided between the LO input and an output of the plurality of switching transistors.
