Chapter 1. Introduction to RF and Wireless Technology
Compare two RF transceivers designed for cell phones:
“A 2.7-V GSM RF Transceiver IC” [1] (published in 1997)
“A Single-Chip 10-Band WCDMA/HSDPA 4-Band GSM/EDGE SAW-Less CMOS Receiver with DigRF 3G Interface and +90-dBm IIP2” [2] (published in 2009)
Why is the latter much more complex than the former? Does the latter have a higher performance or only greater functionality? Which one costs more? Which one consumes a higher power? What do all the acronyms GSM, WCDMA, HSDPA, EDGE, SAW, and IIP2 mean? Why do we care?
The field of RF communication has grown rapidly over the past two decades, reaching far into our lives and livelihood. Our cell phones serve as an encyclopedia, a shopping terminus, ...
