Abstract
A combination mixer arrangement comprising a first mixer and a second mixer coupled in parallel between first and second input ports and an output port. The mixers are arranged to be driven simultaneously by an input signal provided at the second input port. They are de-coupled, so a bias voltage applied at the first input port provides dc bias simultaneously for the mixers to enable gain expansion of the first mixer responsive to an increase in said input signal and thereby an improved linearity for the combination mixer arrangement.
