The Design And Realization Of Wireless RF Receiver Based On TDA5210

It is the main stream that RF (radio frequency) wireless communication systemto the future wireless communication industry. It involves in a few different industriesin both civil and military: from industrial automatic control, wireless traffic control,real-time wireless monitoring, express way check, entrance guard and airport securitycheck, etc. In the first place, what we might observe is the trend that RFcommunication technology develops in speed. Such as RFID and so on, it is involvedby Texas Instruments Motorola and Philips and acquiring different features. Whatworth mentioning is that the RFID technology has a wide range of usage includingindustrial and intelligent traffic control. As is concerned, there might be moreindustries adopt such type of technology. As is concerned, in Europe, the RFmanufactures act as a crucial role in packages check and people travelers dispatching.Since1997, many countries in Europe commend that all newly manufacturedautomobiles are taking whether it contains the burglary-resisting system as thestandard of security check. Also, the similar RF identification and communicationsystems are installed on every train in Sweden. Under this circumstance, thedispatcher of the transporting system may handle the real-time information of thetrains. Thus, from the whole railway system to every single railroad, not only does itbenefit the work of dispatchers but also eliminates the possibility of tragedy. At theend of20’s Century, most of the commute bus are installed with the RFID system. Itis also planning to popularize the system to railway and some other cities. Besides that,the Lufthansa uses the RF card to take place the traditional boarding check and ithugely develops the efficiency of the work. So do BMW and Motorola which adoptthe RF technology to its manufacturing. From this part, the RF technology has itswide marketing range in the future.However, both the theoretical status and the designing difficulties are in higherlevel. It mainly concerns two aspects: The designing and debugging of front-end channel and the using of core chip for transmitting and receiving. The433MHzwireless receiver which is based on TDA5210concerned in this essay is involved inthese two aspects. In this essay we presents detail description to the equipmentfacilitated into TPMS (Tyre pressure monitoring system). At the mean time, itdevelops the designing to the RF circuit to a theoretical level, combining theoreticalcalculation, simulation and results from monitoring, providing systematicaldemonstrating to the RF circuit designing.In this essay, we represent the review of background to RF communication. Itfully represents the dominant role of RF telecommunication in the IT industry. At themean time, it classifies the wireless telecommunication system from the difference indefinition. Thus, it represents the type of the designing as mentioned in this essay.Also, in this essay, we provide basic introduction to the whole designing plan andrelevant simulation software. We classify the wireless RF receiver into differentmodes. It also introduces the theoretical analyzing and calculation to the parameterswhich is aimed at providing benefits to the following analyzing.In the next part, we provide the relevant data to the two different modes. Firstly, wecombine the principle of work to the TDA5210and receiving segment incommunication theory. With the conclusion, under the norm of the design, we presentthe analysis and calculation to the design. In the second place, after the representingof Q value, we provide the definition of Q value in smith chart and the relevant circuit.Then, with the Q value theory, we calculate and compare the three different types ofmatching net. After that, with the concern of microstrip, we provide the sheet of thefinal designing result.In the end, we provide the conclusion and the remaining problems which areremain unsolved. It presents the orientation to the relevant future work.
