In this chapter, the polar transmitter architecture is explored at mm-waves as one proposed disruptive architecture to achieve high PA efficiency at power back-off (Khalaf in IEEE J Solid-State Circuits 99:1–14, [Khalaf16]). Two chips will be presented in the following sections to validate the polar behavior at mm-waves and show the design trade-offs.
