In the high frequency world, the passive technologies required to realize RF and microwave functionality present distinctive challenges. SAW filters, dielectric resonators, MEMS, and waveguide 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. RF and Microwave Passive and Active Technologies provides detailed information about a wide range of component technologies used in modern RF and microwave systems. Updated chapters include new material on such technologies as MEMS, device packaging, surface acoustic wave (SAW) filters, bipolar junction and heterojunction transistors, and high mobility electron transistors (HMETs). The book also features a completely rewritten section on wide bandgap transistors.GaN is another material that is potentially important for MESFET applications. ... a high-saturation velocity (1.5 A 105 m/s), and a high-electron mobility (1000 cm2/ Vs).29a32 Khan et al.33 and Binari ... The motion of these electrons is simulated in the electric field that is calculated self-consistently by solving the Poisson equation iteratively. ... Self-consistent Monte Carlo simulations are very useful for revealing the device physics and verifying novel device concepts and ideas.23, 40a44anbsp;...
