Abstract

In accordance with an embodiment, a phase detector circuit includes a plurality of cascaded RF stages that each has a first RF amplifier and a second RF amplifier. The first RF amplifiers are cascaded with first RF amplifiers of successive RF stages, and the second RF amplifiers are cascaded with second RF amplifiers of successive RF stages. The phase detector further includes a first mixer having a first input coupled to an output of a first RF amplifier of a first RF stage and a second input coupled to an output of a second RF amplifier of the first RF stage, and a second mixer having a first input coupled to an output of a second RF amplifier of a second RF stage and a second input coupled to an output of a first RF amplifier of the second RF stage.
