Gigahertz and Terahertz Technologies for Broadband Communications: Second Edition is a cutting-edge resource for understanding current, emerging, and future broadband communications systems, as well as the industry's major players and their products. This second edition covers more material on the massive and often radical technological developments that have taken place in the past two decades. This book spans RF, optical technology, and engineering at a practical level making it relevant to engineers working on 5G, 6G terrestrial and space and satellite applications. It helps engineers make design critical choices both at component and system level and increases awareness of the specific design challenges that need to be addressed in high frequency RF and fibre and free space optical transmission systems.

The story of the takeover of England's schools by the super-efficient, modernising, academising machine.

Roger Crandle is missing time. Thirty years old, skint, out of work, he lives in a small council flat in South London. Deborah, an American hypnotherapist, offers to help him recover his lost memories. Fifty-six years old by the calendar, she looks around twenty-five, Roger finds himself inexplicably drawn to her. And why is Henry, his curious double with strange powers, apparently stalking him? Henry mingles with aliens on the moon and borrows their flying saucers to get around. A group of secret agents from a mysterious 'Black' organisation is trying to eliminate him. Another group is protecting him. To complicate matters Henry falls in love with Jensine, a female psychiatrist, providing Black Ops agents a perfect way to blackmail him. How are Roger and Henry connected? Will Roger resolve the secret of his missing time?

This book explains how to design various amplifiers, circuits, and chips for communication systems and select the appropriate ADC and DAC technology. It covers RF semiconductors, and includes details on passive RF components, capacitors, inductors, resistors, transmission, coaxial, and microstrip lines as well as coplanar waveguide.
