High-temperature superconducting (HTS) materials are becoming more and more attractive in the context of designing RF/microwave filters because of their lower losses and excellent performance. This book focuses on the superconducting microwave filter and its application in modern communication. It first presents the basic principles, HTS materials and processing and then introduces several types of multi-band HTS bandpass filter (BPF), discussing their properties and analyzing equivalent circuit models and their performances. This book is a valuable resource for students and researchers who are interested in wireless communication and RF/microwave design.

<i>Reconfigurable RF Power Amplifiers on Silicon for Wireless Handsets</i> is intended to designers and researchers who have to tackle the efficiency/linearity trade-off in modern RF transmitters so as to extend their battery lifetime. High data rate 3G/4G standards feature broad channel bandwidths, high dynamic range and critical envelope variations which generally forces the power amplifier (PA) to operate in a low efficiency “backed-off” regime. Classic efficiency enhancement techniques such as Envelope Elimination and Restoration reveal to be little compliant with handset-dedicated PA implementation due to their channel-bandwidth-limited behavior and their increased die area consumption and/or bill-of-material. The architectural advances that are proposed in this book circumvent these issues since they put the stress on low die-area /low power-consumption control circuitry. The advantages of silicon over III/V technologies are highlighted by several analogue signal processing techniques that can be implemented on-chip with a power amplifier. System-level and transistor-level simulations are combined to illustrate the principles of the proposed power adaptive solutions. Measurement on BICMOS demonstrators allows validating the functionality of dynamic linearity/efficiency management. In <i>Reconfigurable RF Power Amplifiers on Silicon for Wireless Handsets</i>, PA designers will find a review of technologies, architectures and theoretical formalisms (Volterra series…) that are traditionally related to PA design. Specific issues that one encounters in power amplifiers (such as thermal / memory effects, stability, VSWR sensitivity…) and the way of overcoming them are also extensively considered throughout this book.

Rettungsaktion für einen Teleporter - Mausbiber Gucky begegnet seinem negativen Ich Perry Rhodan gelang etwas, das niemand mehr für möglich gehalten hatte! Der Großadministrator kehrte in letzter Sekunde nach Terra zurück und wurde am 1. August 3444 durch das Votum der wahlberechtigten Bürger des Solaren Imperiums erneut mit beeindruckender Mehrheit in seinem Amt bestätigt. Seit jenem denkwürdigen Tage haben zwei weitere Wahlen stattgefunden, und Perry Rhodan ist nach wie vor Großadministrator. Seine alte und vertraute Mannschaft - die unsterblichen Aktivatorträger eingeschlossen - steht ihm treu zur Seite. Jetzt, Anfang September des Jahres 3456, gibt es im Solaren Imperium weder politische noch militärische Schwierigkeiten. Handel und Industrie, Wissenschaft und Technik blühen, Fortschritte auf vielen Gebieten bahnen sich an. Und im Zuge eines dem raumfahrttechnischen Fortschritt dienenden Experiments hat Perry Rhodan die "unsichtbare Grenze" überschritten. Mit der MARCO POLO und 8500 seiner Gefährten gelangte der Großadministrator überraschend in ein Paralleluniversum und auf eine parallele Erde, die wie das Privatgefängnis eines brutalen und machtgierigen Diktators wirkt. Die MARCO POLO konnte der Albtraumwelt Terra II entfliehen. Doch der Teleportermutant Ras Tschubai blieb zurück. Auf seine Rettung sind Perry Rhodans Bemühungen gerichtet. Mausbiber Gucky wird losgeschickt, und sein Unternehmen gipfelt in dem SPRUNG NACH LUNA ...

"Wake of War is packed with intense, realistic combat action set in an all-too-believable near future. Zac Topping has clearly been there and done that, and he delivers riveting combat scenes that explode off of the page." - Michael Mammay, author of Generation Ship In the future, the fate of America will be decided in a valley of death… The year is 2037, and chaos reigns. The U.S. government is in the hands of a borderline fascist who rules a country that is falling apart. Economic collapse looms, whole populations are fleeing their homes, and the armed forces are caught in a seemingly helpless war. Their foe—their own countrymen. The Revolutionist Front was borne of the government's increasingly draconian actions. But the RF is equally extreme, run by a merciless megalomaniac determined to create his own version of America. Now, both armies find themselves in a stalemate in Salt Lake City, facing each other across a vital resource mine that could decide the outcome of the war. In this maelstrom, three fighters will experience the horrors of war from different directions: a young, green infantryman about to receive his baptism of fire; a ruthless rebel sniper out to make her enemies pay for what they took from her; and a hardened mercenary being paid to protect the mine. Each will be tested to the limits of their loyalties and personal honor. But none will emerge from the coming battle the same as when they walked into hell on earth… "Topping, a U.S. Army veteran, pays attention to moral issues while taking care not to overly demonize either side, but it's the heroic characters and meticulously rendered battle scenes that make this a standout. This is a must for fans of the genre." - Publishers Weekly, STARRED review! "Topping, who has served two tours in Iraq, does a phenomenal job of using dialogue and scene details to impart the raw and dangerous wartime conditions that surround his characters... Wake of War will resonate with all readers who enjoy thrillers that reflect real-world crises." - Chika Gujarathi, Book Page "Wake of War, the new military thriller from Zac Topping, reaches beyond the action to be both timely and quite ambitious. This book looks past the battlefield to examine just how far those with power will go to keep it." - The Big Thrill "I love a good military thriller and this was no exception! It was full of fast-paced fighting, backstories on the characters and a rebellion to add to the intrigue." - The Open Books, 4 out of 5 stars
