General Description

The MAX7033 fully integrated low-power CMOS super-

heterodyne receiver is ideal for receiving amplitude-

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

frequency range. The receiver has an RF input signal

range of -114dBm to 0dBm. With few external compo-

nents and a low-current power-down mode, it is ideal

for cost-sensitive and power-sensitive applications typi-

cal in the automotive and consumer markets. The

MAX7033 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 ana-

log baseband data-recovery circuitry. The MAX7033

also has a discrete one-step automatic gain control

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

input signal exceeds -62dBm. The AGC circuitry offers

an externally controlled hold feature.

The MAX7033 is available in a 28-pin TSSOP package

and is specified over the extended (-40°C to +105°C)

temperature range.
