RF Receiverscrowded air space, separate it from the rest of the frequency spectrum, and extract a message. Hence, the literal implementation of the receiver function, which is known as a TRF receiver, consists only of a receiving antenna, an RF amplifier, and an audio amplifier. On the other hand, advanced radi

Transistor Biasing Depending on the specific shape of a non-linear function, this dynamic (i.e. AC) resistance is very much dependent on the function’s curvature at the given static point, that is to say on its derivative. In this section we review basic technique to choose and setup DC and AC resistances of active devices, in a process known as the biasing setup.

Review of Basic Amplifiers IF amplifiers. Aside from their operating frequency, for all practical purposes, there is not much difference between the schematic diagrams of RF and IF amplifiers. In this book, unless we need to specifically separate the two functions, we refer to all tuned amplifiers as RF amplifiers.

Introduction to Frequency Analysis of AmplifiersHowever, once the rate of change is sufficiently increased, the delays are not negligible anymore and we must account for the time that circuits need to respond after given a stimuli. In this chapter we review basic techniques of “frequency analysis” that are appropriate for low to medium frequencies.

Frequency Shiftingthe process of shifting a lower frequency tone to the upper frequency range (used in RF transmitters), while “downconversion” refers to the frequency shifting from higher to lower frequency ranges (used in RF receivers). Hence, in a complete wireless communication system, the information-carrying signal is shifted in both directions.

Introductioncal. This chapter introduces fundamental concepts and definitions in physics, mathematics, and engineering with the intention of preparing you, the reader, for the material that follows; in return, that material is expected to reduce, if not completely remove, the “magic” part of the subject.
