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.
