MAX1473 - ASK Superheterodyne Receiver

MAX1473 Description

www.DataSheet4U.com 19-2748; Rev 3; 11/03 315MHz/433MHz ASK Superheterodyne Receiver with Extended Dynamic Range General .
The MAX1473 fully integrated low-power CMOS superheterodyne receiver is ideal for receiving amplitudeshift-keyed (ASK) data in the 300MHz to 450MHz fr.

MAX1473 Features

* o Optimized for 315MHz or 433MHz ISM Band o Operates from Single 3.3V or 5.0V Supplies o High Dynamic Range with On-Chip AGC o Selectable Image-Rejection Center Frequency o Selectable x64 or x32 fLO/fXTAL Ratio o Low 5.2mA Operating Supply Current o

MAX1473 Applications

* typical in the automotive and consumer markets. The chip consists of a low-noise amplifier (LNA), a fully differential image-rejection mixer, an onchip phase-locked-loop (PLL) with integrated voltagecontrolled oscillator (VCO), a 10.7MHz IF limiting amplifier stage with received-signal-strength indi
