This book, RF and Microwave Passive and Active Technologies, provides detailed information about a wide range of component technologies used in modern RF and microwave systems. Passive technologies required to realize RF or microwave functionality are often unique to the high frequencyworld. SAWfilters, dielectric resonators, MEMS, and waveguides do not have counterparts in the low frequency or digital environment. Even when conventional lumped components can be used in high frequency applications, their behavior does not resemble that observed at lower frequencies. These issues are discussed in individual chapters. Unique microwave packaging and antenna considerations are also explored
