This chapter discusses the application of a novel switched mode Class-E PA implemented in 22 nm FDSOI technology. The Class-E PA relies on switching not only the input device, but also the cascode device with a 50% duty cycle signal in order to minimize the overlap between the output voltage and the current (pulse injection). Not only will the cascode device be switched, but an added delay element between the input and output transistors is employed. This modification of the delayed phase will result in more control over the power consumption and hence the DE and PAE. This chapter is organized as follows: Sect. 4.1 discusses the switched cascode Class-E PA design and architecture. Followed by Sect. 4.2 that presents the implementation and measurement results. Section 4.3 provides a summary.
