Claim 5:
6. A radar transceiver, comprising:
a receiver, comprising:
an amplifier including an output;
a mixer comprising an input coupled to the output of the amplifier, wherein the mixer further comprises an output;
a baseband filter comprising an input coupled to the output of the mixer, the input of the baseband filter configured to receive a quadrature (Q) phase component of an oscillating signal, wherein the baseband filter further comprises an output;
an analog integrator comprising an input coupled to the output of the baseband filter, wherein the analog integrator further comprises an output, the analog integrator configured to output a control signal at the output of the analog integrator; and
a phase shifter comprising:
a signal input configured to receive an oscillating signal;
a control input coupled to the output of the analog integrator and configured to receive the control signal; and
an output coupled to the mixer;

wherein the baseband filter and the analog integrator form an analog feedback path between the output of the mixer and the control input of the phase shifter.
