An RF front-end receiver comprises a low noise amplifier and a local
oscillator driver, which are connected to respective input ports of a
mixer which comprises a first and second transistor with gates coupled to
one output terminal, a third and fourth transistor with gates coupled to
the other output terminal, a fifth and sixth transistor with gates
coupled to respective output terminal of the local oscillator driver, the
sources of the first and third transistors coupled to the drain of the
fifth transistor, the sources of the second and fourth transistor coupled
to the drain of the sixth transistor, the sources of the fifth and sixth
transistor coupled to ground, the drains of the first and fourth
transistor coupled to one output terminal of a mixer output port, and the
drains of the second and third transistor coupled to the other output
terminal of the mixer output port.
