Stability Analysis of Nonlinear Microwave Circuits
The increasing use of high-frequency integrated circuits monolithic microwave integrated circuits (MMICs) in modern communications systems requires an accurate prediction of their response at the simulation stage because this technology does not allow any circuit modification after manufacturing. The microwave circuits are often designed using frequency-domain techniques, like harmonic balance. With this technique, only the steady state is...

Microwaves are generally considered to be a specific part of the wide radio frequency spectrum. The band from 300 MHz to 30 GHz is typically considered to be “microwaves,” for example by the Institute of Electrical end Electronics Engineers (IEEE), although many of us prefer to set the lower limit somewhat higher—perhaps at 1 or even 3 GHz. Above 30 GHz, the term “millimeter waves” is used. High school physics suggests that we are...

High frequency techniques An Introduction to RF and Microwave Engineering
This book is written for the undergraduate or graduate student who wishes to pursue a career in radio-frequency (RF) and microwave engineering. Today’s engineer must use the computer as a design tool to be competitive. This text presumes that the student has access to a computer and network simulation software, but the book can be used without them. In either event, this text will prepare the student for the modern engineering environment in...

Lumped Elements for RF and Microwave Circuits
A lumped element in microwave circuits is defined as a passive component whose size across any dimension is much smaller than the operating wavelength so that there is no appreciable phase shift between the input and output terminals. Generally, keeping the maximum dimension less thanl /20 is a good approximation where l is the guide wavelength. Lumped elements for use at RF and microwave frequencies are designed on the basis of this...

Radio-Frequency and microwave communication circuits analysis design
Scientists and mathematicians of the nineteenth century laid the foundation of telecommunication and wireless technology, which has affected all facets of modern society. In 1864, James C. Maxwell put forth fundamental relations of electromagnetic fields that not only summed up the research findings of Laplace, Poisson, Faraday, Gauss, and others but also predicted the propagation of electrical signals through space. Heinrich Hertz...
