The CC1101 is a low-cost sub- 1 GHztransceiver designed for very low-powerwireless applications. The circuit is mainlyintended for the ISM (Industrial, Scientific andMedical) and SRD (Short Range Device)frequency bands at 315, 433, 868, and 915MHz, but can easily be programmed foroperation at other frequencies in the 300-348MHz, 387-464 MHz and 779-928 MHz bands.CC1101 is an improved and code compatibleversion of the CC1100 RF transceiver. Themain improvements on the CC1101 include:

過去,RF功率的性能完全取決于線性效率。如今,開發(fā)者遇到更加復(fù)雜的挑戰(zhàn):需要滿足多種標(biāo)準(zhǔn)、信號(hào)變化和嚴(yán)格的帶寬要求等。針對這一問題,飛思卡爾半導(dǎo)體(NYSE:FSL)日前推出新型硅片RF LDMOS功率晶體管Airfast RF功率解決方案,將性能和能效提升至新的高度。飛思卡爾通過新的產(chǎn)品系列解決了這種模式轉(zhuǎn)變帶來的問題,該產(chǎn)品系列基于一種更加全面、完整的系統(tǒng)級(jí)RF功率技術(shù)方法。

The main objective of this book is to present all the relevant informationrequired for RF and micro-wave power amplifier design includingwell-known and novel theoretical approaches and practical design techniquesas well as to suggest optimum design approaches effectively combininganalytical calculations and computer-aided design. This bookcan also be very useful for lecturing to promote the analytical way ofthinking with practical verification by making a bridge between theoryand practice of RF and microwave engineering. As it often happens, anew result is the well-forgotten old one. Therefore, the demonstrationof not only new results based on new technologies or circuit schematicsis given, but some sufficiently old ideas or approaches are also introduced,that could be very useful in modern practice or could contributeto appearance of new ideas or schematic techniques.

When I started writing the first edition of RF Power Amplifiers for Wireless Communications,some time back in 1997, it seemed that I was roaming a largely uninhabitedlandscape. For reasons still not clear to me there were few, if any, otherbooks dedicated to the subject of RF power amplifiers. Right at the same time, however,hundreds of engineers were being assigned projects to design PAs for wirelesscommunications products. It was not, therefore, especially difficult to be successfulwith a book that was fortuitously at the right place and the right time.
