The MAX1470 is a fully integrated low-power CMOS
superheterodyne receiver for use with amplitude-shiftkeyed
(ASK) data in the 315MHz band. With few
required external components, and a low-current
power-down mode, it is ideal for cost- and power-sensitive
applications in the automotive and consumer markets.
The chip consists of a 315MHz low-noise amplifier
(LNA), an image rejection mixer, a fully integrated
315MHz phase-lock-loop (PLL), a 10.7MHz IF limiting
amplifier stage with received-signal-strength indicator
(RSSI) and an ASK demodulator, and analog baseband
data-recovery circuitry.
The MAX1470 is available in a 28-pin TSSOP package.
