CHAPTER 8 RF Front-End Design
Throughout most of this book, we have studied the components that make up RF circuits. Now we put all these pieces together to form one of the most critical subsystems in any communication system—namely, the RF front end. We’ll start by showing where the RF front end fits in today’s modern applications, and then decompose or “tear down” this subsystem into its basic components and functions, many of which have already been covered in earlier chapters. This approach will also provide a logical way to introduce key receiver types and associated performance specifications, such as signal-to-noise ratio (SNR), receiver sensitivity, and selectivity.
The RF front end is part of an overall radio receiver-transmitter or ...
