| Summary: | 碩士 === 中華大學 === 電機工程學系碩士班 === 100 === Because various types of mobile devices become popular, customers using 3.5G services are also increased. Although 3.5G base stations cover widely, the increase of Internet users has resulted in sharp decline in the transmission data rate. Recently, 3.5GHz communication capacity tends to be saturated in metropolitan areas. In order to reduce the burden of data transfer for the 3.5G network, this thesis presents the Wi-Fi Frequency Conversion technology then base station to mobile station communication can uses Wi-Fi protocol in the specified frequency band. It can provide high-speed Internet access needs.
This thesis proposed RF frequency convertor design for broadband wireless network compatible with the 802.11a/g/n standards. The frequency convertor allows input frequency band from 5.15GHz to 5.55GHz and output frequency from 3.4GHz to 3.8GHz which provides 400MHz bandwidth. Frequency convertor design includes system frequency planning and budget analysis. The power amplifier at 3.6GHz can reach 25dBm@2.5%EVM output power and support a long transmission distance over 7 km.
