Presents reprinted tutorial papers on HEMTs, HBTs and heterojunctions, including papers which report major achievements of the HEMT and HBT technologies in the fields of microwave, millimeter-wave and digital ICs.

Based on the 1980 text, Microstrip Antennas, this volume offers information on designing any type of microstrip antenna. In addition to addressing essential microchip antenna theory, the authors highlight current design and engineering practices, emphasizing pressing issues such as broadbanding, circular polarization and active microstrip antennas in particular. Special design challenges, ranging from dual polarization, high bandwidth, and surface wave mitigation, to choosing the proper substrate, and shaping an antenna to achieve desired results are all covered. The book includes more than...

Fully updated and including entirely new chapters, this Second Edition provides in-depth coverage of the different types of RF and microwave circuit elements, including inductors, capacitors, resistors, transformers, via holes, airbridges, and crossovers. Featuring extensive formulas for lumped elements, design trade-offs, and an updated and current list of references, the book helps you understand the value and usefulness of lumped elements in the design of RF, microwave and millimeter wave components and circuits. You'll find a balanced treatment between standalone lumped elements and their...
