<p>A mixer of the commutating type using FETs to switch between the primary of a transformer 1 for an r.f. input and the secondary of a transformer 2 for an i.f. output, has high linearity and low power consumption of the local oscillator drive because the gate electrodes of the FETs are switched using pulse waveforms e.g. from driving transistors 6 to 9. <IMAGE></p> |
