Chapter 6. RF Amplifiers
In this chapter, we take a slight step to the side and get a better understanding of preamplifiers. Typically used to improve receiver performance, these circuits often come just after the antenna. This chapter also provides a significant amount of detail on transistor gain and how to classify amplifier circuits.—Janine Sullivan Love
In this chapter we will take a look at small signal radio frequency amplifiers and preamplifiers. These circuits are used to amplify radio signals from antennas prior to input to the mixer, in order to improve signal-to-noise ratio and front-end selectivity. A preamplifier is simply an RF amplifier which is external to the receiver, rather than being built in.
The performance of some radio ...
