RADIO-FREQUENCY AND MICROWAVE COMMUNICATION CIRCUITS
Wireless technology continues to grow at a tremendous rate, with new applications still reported almost daily. In addition to the traditional applications in communications, such as radio and television, radio-frequency (RF) and microwaves are being used in cordless phones, cellular communication, local area networks, and personal communication systems. Keyless door entry, radio-frequency identification, monitoring of patients in a hospital or...

The handbook of optical communication networks
These factors are leading towards an integrated high-speed (and high-bandwidth) communication environment where all communication needs will be supported by a single communication network. The latest trends indicate that bandwidth needs double every 100 days. The volume of data traffic has surpassed the volume of voice traffic. Such a monumental demand for bandwidth can only be met by using optical fiber as transmission media. Other...

Smart antennas involve processing of signals induced on an array of sensors such as antennas, microphones, and hydrophones. They have applications in the areas of radar, sonar, medical imaging, and communications. Smart antennas have the property of spatial filtering, which makes it possible to receive energy from a particular direction while simultaneously blocking it from another direction. This property makes smart antennas a very effective...

Networks and devices using planar transmissions lines
By “planar transmission line” we mean a transmission line whose conductors are on planes. Examples are microstrips and slotlines. By “device” we mean a component that is capable of having some electrical property in addition to the obvious “RF” connecting characteristic. Examples are directional couplers and phase shifters. All the devices we will study are made of planar transmission lines. By “network” we mean a set of...

Underlying many of the current mathematical opportunities in digital signal processing are unsolved analog signal processing problems. For instance, digital signals for communication or sensing must map into an analog format for transmission through a physical layer. In this layer we meet a canonical example of analog signal processing: the electrical engineer’s impedance matching problem. Impedance matching is the design of analog signal...

There have been many advances in communication circuits since the publication of the first edition of this book. Yet most of the communication circuit fundamentals remain intact. Amplifiers, oscillators, tuned circuits, transformers, mixers, and power amplifiers are still among the fundamental building blocks of communication circuits.

Microstrip Filters for RF/Microwave Applications
Filters play important roles in many RF/microwave applications. Emerging applications such as wireless communications continue to challenge RF/microwave filters with ever more stringent requirements—higher performance, smaller size, lighter weight, and lower cost. The recent advances in novel materials and fabrication technologies, including high-temperature superconductors (HTS), low-temperature cofired ceramics (LTCC), monolithic...

Handbook on satellite communications (HSC)
Satellite communications now form an integral part of our new "wired" world. Since their introduction in about 1965, satellite communications have generated a multiplicity of new telecommunication or broadcasting services on a global or regional basis. In particular, they have enabled a global, automatically-switched telephony network to be created. Although, since 1956 (TAT1), submarine cables began to operationally connect the continents of...
