The MAX1471 low-power, CMOS, superheterodyne, RF

dual-channel receiver is designed to receive both ampli-

tude-shift-keyed (ASK) and frequency-shift-keyed (FSK)

data without reconfiguring the device or introducing any

time delay normally associated with changing modula-

tion schemes. The MAX1471 requires few external com-

ponents to realize a complete wireless RF digital data

receiver for the 300MHz to 450MHz ISM bands.

The MAX1471 includes all the active components

required in a superheterodyne receiver including: a low-

noise amplifier (LNA), an image-reject (IR) mixer, a fully

integrated phase-locked loop (PLL), local oscillator

(LO), 10.7MHz IF limiting amplifier with received-signal-

strength indicator (RSSI), low-noise FM demodulator,

and a 3V voltage regulator. Differential peak-detecting

data demodulators are included for both the FSK and

ASK analog baseband data recovery. The MAX1471

includes a discontinuous receive (DRX) mode for low-

power operation, which is configured through a serial

interface bus.

The MAX1471 is available in a 32-pin thin QFN package

and is specified over the automotive -40°C to +125°C

temperature range.
