315MHz/434MHz ASK Superheterodyne Receiver

300MHz to 450MHz Superheterodyne ASK Receiver with Integrated Image Rejection Operates Up to +125°C

Please check latest availability status for a specific part variant.


The MAX7034 fully integrated low-power CMOS super-heterodyne receiver is ideal for receiving amplitude-shift-keyed (ASK) data in the 300MHz to 450MHz frequency range (including the popular 315MHz and 433.92MHz frequencies). The receiver has an RF sensitivity of -114dBm. With few external components and a low-current power-down mode, it is ideal for cost-sensitive and power-sensitive applications typical in the automotive and consumer markets. The MAX7034 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 MAX7034 is available in a 28-pin (9.7mm x 4.4mm) TSSOP package and is specified over the automotive (-40°C to +125°C) temperature range.
