CommunicationsFeatured products260MHz to 470MHz ISM radio for HANs and NANs extends battery life up to seven yearsMAX7032BenefitsThe MAX7032 transceiver offers an inexpensive, low-power solutionfor one-way and two-way reporting from meters in HANs and someNANs. The transceiver uses the license-free low-frequency radiobands in the U.S. (260MHz to 470MHz) and Europe (433.05MHz to434.79MHz). The radio’s simple ASK or FSK modulation technique,outstanding sensitivity, wide selection of data rates, and low currentdrain make it the perfect choice for local radio links and networksin these frequency ranges. The transceiver can achieve link marginsbetter than 120dB, which means that it can reach 1km over open flatterrain or maintain a link between an underground water meter anda local concentrator. The MAX7032 is flexible enough to work withmultiple smart grid communication standards.••Extends battery life––Low active (< 7mA Rx, < 12mA Tx) andshutdown (< 1µA) current extendsbattery life––Programmable receiver shutdown/wake-up cycle for additional currentsavings••Compact radio module for spaceconstrainedmetering applications––Small 5mm x 5mm TQFN package••Good penetration in buildingsMETER SENSOR (WATER ORGAS VOLUME, FLOW, ETC.)µPCRYSTALSCLK DIO CSBTX/RX1DATAMETER OR READERKEYPAD/CONTROLLERANTENNAMATCHINGNETWORKPAOUTLNAINMAX7032TRANSCEIVERHVINAVDDDVDDSUPPLY,BYPASSV DDMETER OR READERDISPLAY4 Ls4 CsLNASRCLNAOUTCERAMICIF FILTERDATA FILTER ANDDETECTOR2 Rs4 CsV DDSystem diagram for the MAX7032.34 <strong>Maxim</strong> <strong>Smart</strong> <strong>Grid</strong> <strong>Solutions</strong>
