MAX1473

315MHz/433MHz ASK Superheterodyne

Receiver with Extended Dynamic Range

General Description

Features

The MAX1473 fully integrated low-power CMOS

superheterodyne receiver is ideal for receiving amplitude-

shift-keyed (ASK) data in the 300MHz to 450MHz frequency

range. Its signal range is from -114dBm to 0dBm. With few

external components and a low-current power-down mode,

it is ideal for cost- and power-sensitive applications typical

in the automotive and consumer markets. The chip consists

of a low-noise ampliﬁer (LNA), a fully diﬀerential image-

rejection mixer, an on-chip phase-locked-loop (PLL) with

integrated voltage-controlled oscillator (VCO), a 10.7MHz IF

limiting ampliﬁer stage with received-signal-strength indicator

(RSSI), and analog baseband data-recovery circuitry. The

MAX1473 also has a discrete one-step automatic gain

control (AGC) that drops the LNA gain by 35dB when the RF

input signal is greater than -57dBm.

● Optimized for 315MHz or 433MHz ISM Band

● Operates from Single 3.3V or 5.0V Supplies

● High Dynamic Range with On-Chip AGC

● Selectable Image-Rejection Center Frequency

● Selectable x64 or x32 f /f

Ratio

LO XTAL

● Low 5.2mA Operating Supply Current

● < 2.5μA Low-Current, Power-Down Mode for Efficient

Power Cycling

● 250μs Startup Time

● Built-In 50dB RF Image Rejection

● Receive Sensitivity of -114dBm

Ordering Information

The MAX1473 is available in 28-pin TSSOP and 32-pin

thin QFN packages. Both versions are speciﬁed for the

extended (-40°C to +85°C) temperature range.
