Microwave filter design has been a persistent and productive field for investigation from the very beginning of microwave engineering. Nowadays advancements in communications systems, in conjunction with the great increasing request for miniaturization and size reduction of wireless systems and devices, have led to an increase of performances and space reduction of modern communications systems and devices. Several RF building blocks have consequently been successfully implemented as integrated circuits (ICs) with different technologies. In this scenario, analog tunable filters working, in general, at RF and microwave frequencies still remain the most difficult part to be integrated in a single chip due to requirements in input and output impedance matching, stability, and dynamic range. In fact, most commercial wireless receivers only use off-chip filters that are typically implemented with discrete components. This scenario leads to the occupation of a large area at the front-end. One of the greatest challenges facing RF and microwave engineering, however, is the increasing level of abstraction needed to create innovative microwave and RF systems. RFID today is the popular wireless induction system. Each RFID tag in RFID system is given a unique ID (UID) which records the on demand information. Many tracking applications based on ubiquitous computing and communication technologies have been presented in recent years such as RFID systems. Therefore, RFID can be used to trace objects and asset worldwide. Due to the popularity of RFID, many local or small area wireless applications were also proposed in this book. Microwave and RF Design is intended to introduce cutting-edge understanding the basic theory of microwave filters, to describe how to design practical microwave filters, and to investigate ways of implementing high performance filters for modern communication systems. The book reviews recent advances and emerging technologies in the RF and microwave area. Examples of modeling techniques and RF circuit applications are presented. Focusing on RF and microwave band-pass passive filters required for mobile transceiver front-ends, it provides calibration methods of RF and microwave power sensor with system setup, modeling, equations, and analyses in different representations, traceability and measurement uncertainty evaluations.
