Highlighting the challenges RF and microwave circuit designers face in their day-to-day tasks, RF and Microwave Circuits, Measurements, and Modeling explores RF and microwave circuit designs in terms of performance and critical design specifications. The book discusses transmitters and receivers first in terms of functional circuit block and then examines each block individually. Separate articles consider fundamental amplifier issues, low noise amplifiers, power amplifiers for handset applications and high power, power amplifiers. Additional chapters cover other circuit functions including oscillators, mixers, modulators, phase locked loops, filters and multiplexers.

New chapters discuss high-power PAs, bit error rate testing, and nonlinear modeling of heterojunction bipolar transistors, while other chapters feature new and updated material that reflects recent progress in such areas as high-volume testing, transmitters and receivers, and CAD tools.

The unique behavior and requirements associated with RF and microwave systems establishes a need for unique and complex models and simulation tools. The required toolset for a microwave circuit designer includes unique device models, both 2D and 3D electromagnetic simulators, as well as frequency domain based small signal and large signal circuit and system simulators. This unique suite of tools requires a design procedure that is also distinctive. This book examines not only the distinct design tools of the microwave circuit designer, but also the design procedures that must be followed to use them effectively.

In a rapidly changing world, the central missionary vision of the church must be constantly renewed, lest its foundations become lost in the confusion of change or its practices trapped in missionary models of the past.

In this second edition of Missions, long-time missionary Gailyn Van Rheenen revises and updates his classic text on Christian missions, laying sound theological and strategic foundations for the missionary of today and tomorrow.

Van Rheenen helps renew the missionary vision by discussing areas such as:

• The history of Christian mission, and how it affects where we are today
• Spiritual formation for God s mission
• The missionary cycle
• Cross-cultural communication
• The character and calling of missionaries
• Types of missionaries
• Church maturation
• Selecting mission fields
• The role of money in missions
• Four levels of involvement in missions

But Missions is more than blackboard theory. Written by a long-time missionary, it carries the conviction and insights of one who has lived his subject. Accessible to students, practitioners, and laypeople alike, Missions provides a primary go-to resource for understanding and becoming involved in the dynamic activity of world missions."

A psychological thriller set in the West Indies in the 1970s. David Beauchamp goes to the island of St Cats to teach science but soon finds himself embroiled in a strange world of full-moon parties, creole aristocrats, and voodoo adepts in a fast-moving tale that will keep you up half the night finishing it.

Supernatural horror set in the Wild West. A band of brave pioneers sets out to find and recover a family of settlers that appears to have been abducted following an attack on a frontier homestead. Expecting the offenders to be the usual posse of hostile natives, the group prepares for routine battle. But as men start to vanish mysteriously and hideous evidence begins to accumulate, the men realise that their enemy may not be merely human after all...
