Mixer

A mixer, comprising:

• a first and a second transistor having their gates coupled to a first input terminal of a mixer input port for receiving a local oscillator signal;
• a third and a fourth transistor having their gates coupled to a second input terminal of the mixer input port for receiving the local oscillator signal;
• a fifth and a sixth transistor having their gates coupled to a first and a second input terminal, respectively, of a mixer input port for receiving a radio frequency signal;
• the sources of the second and fourth transistor being coupled to the drain of the sixth transistor;
• the sources of the fifth and sixth transistor being coupled to ground;
• the drains of the first and fourth transistor being coupled to one output terminal of a mixer output port for an intermediate frequency signal;
• and
• the drains of the second and third transistor being coupled to the other output terminal of the mixer output port;
• wherein
• the gates of the first and second transistors and the gates of the third and fourth transistors are coupled to the first and second input terminals of the mixer input port for the local oscillator signal, respectively, via respective separate passive low pass filters.
