Detailed Description
The MAX7033 CMOS superheterodyne receiver and a
few external components provide the complete receive
chain from the antenna to the digital output data.
Depending on signal power and component selection,
data rates as high as 33kbps Manchester (66kbps
NRZ) can be achieved.
The MAX7033 is designed to receive binary ASK data
modulated in the 300MHz to 450MHz frequency range.
ASK modulation uses a difference in amplitude of the
carrier to represent logic 0 and logic 1 data.
Voltage Regulator
For operation with a single +3.0V to +3.6V supply voltage,
connect AVDD, DVDD, and V DD5 to the supply voltage.
For operation with a single +4.5V to +5.5V supply voltage,
connect V DD5 to the supply voltage. An on-chip voltage
regulator drives one of the AVDD pins to approximately
+3.2V. For proper operation, DVDD and both the AVDD
pins must be connected together. Bypass V DD5 , DVDD,
and the pin 7 AVDD pin to AGND with 0.01μF capacitors,
and the pin 2 AVDD pin to AGND with a 0.1μF capacitor,
all placed as close as possible to the pins.
Low-Noise Amplifier
The LNA is an nMOS cascode amplifier with off-chip
inductive degeneration, with a 3.0dB noise figure and
an IIP3 of -12dBm. The gain and noise figures are
dependent on both the antenna matching network at
the LNA input and the LC tank network between the
LNA output and the mixer inputs.
