Emergency Radio Frequency

Remarkable developments in bipolar technology over the past decade have seen the silicon germanium heterojunction bipolar transistor (SiGe HBT) emerge from research labs to enter production in radio frequency technologies. These developments have allowed SiGe BiCMOS transistors to address high-frequency wireless and optical communications applications that were previously only possible in III/V and II/VI devices. This book brings together for the first time all the new developments and describes in a unified manner the physics, materials science and technology of silicon bipolar transistors and SiGe HBTs. Featuring: Basic device physics concepts presented in a simple and concise way.All the key technology innovations in detail, including polysilicon emitters, selective implanted collectors, selective and differential SiGe(C) epitaxy, and technology case studies.Compact models of bipolar transistors, including Gummel Poon, Mextram and VBIC.Overall bipolar technology, device and circuit optimisation. "SiGe Heterojunction Bipolar Transistors is an essential tool for practising process engineers and integrated circuit designers in the semiconductor, optical communications and wireless communications industries. University researchers, scientists and postgraduates students in microelectronics, semiconductors and electronic engineering will find this book an invaluable reference. Professor Ashburn has worked as an industrial engineer, a consultant and a university professor and has accumulated a wealth of practical knowledge for incorporation in this book.

Developments in RFID (Radio-Frequency Identification) are yielding larger memory capacities, wider reading ranges and quicker processing, making it one of fastest growing sectors of the radio technology industry. RFID has become indispensable in a wide range of automated data capture and identification applications, from ticketing and access control to industrial automation. The second edition of Finkenzeller's comprehensive handbook brings together the disparate information on this versatile technology. Features include: Essential new information on the industry standards and regulations, including ISO 14443 (contactless ticketing), ISO 15693 (smartlabel) and ISO 14223 (animal identification).Complete coverage of the physical principles behind RFID technologies such as inductive coupling, surface acoustic waves and the emerging UHF and microwave backscatter systems.A detailed description of common algorithms for anticollision.An exhaustive appendix providing listings of RFID associations, journals and standards. A sample test card layout in accordance with ISO 14443.Numerous sample applications including e-ticketing in public transport systems and animal identification.End users of RFID products, electrical engineering students and newcomers to the field will value this introduction to the functionality of RFID technology and the physical principles involved. Experienced ADC professionals will benefit from the breadth of applications examples combined within this single resource.

Aircraft emergency frequency - The aircraft emergency frequency is a frequency used on the aircraft radio band reserved for emergency communications for aircraft in distress. The frequencies are 121.

Ground Wave Emergency Network - The Ground Wave Emergency Network (GWEN) is an array of radio transceivers distributed across the continental USA, operating in the VLF frequency band, and intended for military communications during a nuclear war.

High-energy radio-frequency weapons - High Energy Radio Frequency weapons (HERF) or High Power Radio Frequency weapons (HPRF) are weapons that use high intensity radio waves to disrupt electronics. They operate similarly to EMP devices, by inducing destructive voltage within electronic wiring.

Radio Amateur Civil Emergency Service - RACES (Radio Amateur Civil Emergency Service) is provided for in Part 97 of the FCC rules and regulations governing amateur radio in the United States. RACES members, volunteer Amateur Radio Operators, operate on behalf of a public agency during a declared emergency, including natural and man-made hazardous situations.
