General Description
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.
