Radio Frequency Circuit Design

The cellular telephone has become a symbol for the rapid change in the communications business. Within this plastic container reside the talents of engineers working in the areas of efficient power supplies, digital circuit design, analog circuit design, semiconductor device design, antennas, linear systems, digital signal processing, packaging, and materials science. All these talents are carefully coordinated at a cost that allows a wide cross section of the world’s population to have available instant communication. The particular aspect of all these activities that is of primary focus in this text is in the area of analog circuit design, with primary emphasis on radio frequency electronics. Some topics normally considered in electronics courses or in microwave and antenna courses are not covered here. For example, there is no mention of distributed branch line couplers, since at 1 GHz their size would be prohibitive. On the other hand, topics such as transmission line transformers are covered because they fit so well into this frequency range.
