Abstract
A mixer is disclosed. The mixer comprises a high isolation gain stage and an impedance transformation network coupled to the gain stage. The mixer includes a plurality of switching devices coupled to the network and a phase shifter coupled to the plurality of switching devices. The mixer is utilized as a receiver and a low noise amplifier is not needed. A receiver in accordance with the present invention achieves high gain and low noise in the mixer and therefore eliminates the need for a separate LNA. In so doing, an isolation gain stage achieves high gain, and image noise is rejected before entering the mixer stage.
