Product Summary

The MAX1472AKA+T is a crystal-referenced phase-locked loop (PLL) VHF/UHF transmitter designed to transmit OOK/ASK data in the 300MHz to 450MHz frequency range. The MAX1472AKA+T supports data rates up to 100kbps, and adjustable output power to more than +10dBm into a 50Ω load. The crystal-based architecture of the MAX1472AKA+T eliminates many of the common problems with SAW transmitters by providing greater modulation depth, faster frequency settling, higher tolerance of the transmit frequency, and reduced temperature dependence. Combined, these improvements enable better overall receiver performance when using a superheterodyne receiver such as the MAX1470 or MAX1473. The applications of the MAX1472AKA+T are (1)Remote Keyless Entry; (2)RF Remote Controls; (3)Tire Pressure Monitoring; (4)Security Systems; (5)Radio-Controlled Toys; (6)Wireless Game Consoles; (7)Wireless Computer Peripherals; (8)Wireless Sensors.
