Summary

This chapter begins with an overview of microwave communication systems and the radio frequency wireless services to illustrate the applications of circuits and devices that are described in the rest of the book. A short discussion on antennas is included to help in understanding the signal behavior when it propagates from transmitter to the receiver. The Friis transmission formula and the radar range equation are important in order to understand effects of frequency, range, and operating power levels on the performance of a communication system. A brief discussion on Doppler radar is also included in this chapter. Noise and distortion characteristics play a significant role in analysis and design of these systems. Minimum detectable signal (MDS), gain compression, intercept-point, and the dynamic range of an amplifier (or the receiver) are subsequently introduced. Other concepts associated with the noise and distortion characteristics are also introduced in this chapter.
