315MHz/434MHz ASK Superheterodyne
General Description
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 sensi-
tivity of -114dBm. With few external components and a
low-current power-down mode, it is ideal for cost-sensi-
tive and power-sensitive applications typical in the
automotive and consumer markets. The MAX7034 con-
sists 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.
