MAX1470

315MHz Low-Power, +3V Superheterodyne

Receiver

General Description

The MAX1470 is a fully integrated low-power CMOS

superheterodyne receiver for use with amplitude-shift-

keyed (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 applica-

tions in the 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.
