MAX1471 Description
The MAX1471 low-power, CMOS, superheterodyne, RF dual-channel receiver is designed to receive both amplitude-shift-keyed (ASK) and frequency-shift-keyed (FSK) data without reconfiguring the device or introducing any time delay normally associated with changing modulation schemes. The MAX1471 requires few external ponents to realize a plete wireless RF digital data receiver for the 300MHz to 450MHz ISM bands. The...
