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...

Introduction to RF propagation
With the rapid expansion of wireless consumer products, there has been a considerable increase in the need for radio-frequency (RF) planning, link planning, and propagation modeling.A network designer with no RF background may find himself/herself designing a wireless network. A wide array of RF planning software packages can provide some support, but there is no substitute for a fundamental understanding of the propagation process and the...

Feedback Linearization of RF Power Amplifiers
Research activity in the area of radio-frequency (RF) circuit design has surged in the last decade in direct response to the enormous market demand for inexpensive, portable, high data rate wireless transceivers. Our expectations for such transceivers, such as cellular phones, rise as they become seemingly ubiquitous. Once, the simple fact of a fairly reliable wireless voice connection was sufficient and even exciting. Now, crystal-clear voice...

Distortion in RF power amplifiers
This book is about nonlinear distortion in radio frequency (RF) power amplifiers (PAs). The purpose of the PA is to boost the radio signal to a sufficient power level for transmission through the air interface from the transmitter to the receiver. This may sound simple, but it involves solving several contradicting requirements, the most important of which are linearity and efficiency. Unfortunately, these requirements tend to be mutually...

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...

Radio frequency integrated circuit design
Radio frequency integrated circuit (RFIC) design is an exciting area for research or product development. Technologies are constantly being improved, and as they are, circuits formerly implemented as discrete solutions can now be integrated onto a single chip. In addition to widely used applications such as cordless phones and cell phones, new applications continue to emerge. Examples of new products requiring RFICs are wireless local-area...
