Abstract: This application note illustrates an intermediate 8V switching power supply for an automotive radio and infotainment system.The design withstands the complete automotive input voltage range (including cold crank and load dump conditions), assuring a stable8V supply for common subsystems such as a CD driver, LCDs, and a radio module in modern infotainment systems. To avoiddisturbance in the AM and FM bands, the switching power supply runs at a fixed frequency of 2MHz, enabling an ideal solution forradio systems.

Abstract: The process of designing a radio system can be complex and often involves many project tradeoffs. Witha little insight, balancing these various characteristics can make the job of designing a radio system easier. Thistutorial explores these tradeoffs and provides details to consider for various radio applications. With a focus on theindustrial, scientific, medical (ISM) bands, the subjects of frequency selection, one-way versus two-way systems,modulation techniques, cost, antenna options, power-supply influences, effects on range, and protocol selectionare explored.

Abstract: This application note discusses a design for a phantom antenna power-supply system compatible with theDigital Satellite Equipment Control (DiSEqC) communication standard, using the MAX16948 automotive dual, highvoltageLDO/switch. The presented application circuit provides a remote antenna power supply and also enables onewaycommunication from the radio head unit to the remote antenna. This system architecture offers flexibility inDiSEqC tone-burst frequency choice (100Hz to 30kHz), enabling users the ability to select the best frequency for theirapplication.

GPRS(General Packet Radio Service)是通用分組無線業(yè)務(wù)的簡稱。GPRS是GSM Phase2.1規(guī)范實(shí)現(xiàn)的內(nèi)容之一，能提供比現(xiàn)有GSM網(wǎng)9.6kbit/s更高的數(shù)據(jù)率。GPRS采用與GSM 相同的頻段、頻帶寬度、突發(fā)結(jié)構(gòu)、無線調(diào)制標(biāo)準(zhǔn)、跳頻規(guī)則以及相同的TDMA幀結(jié)構(gòu)。因此，在GSM系統(tǒng)的基礎(chǔ)上構(gòu)建GPRS系統(tǒng)時，GSM系統(tǒng)中的絕大部分部件都不需要作硬件改動，只需作軟件升級。
