MAX7033 Evaluation Kit
Power Supply
The MAX7033 can operate from 3.3V or 5V supplies.
For 5V operation, remove JU7 before connecting the
supply to VDD. For 3.3V operation, connect JU7.
IF Input/Output
The 10.7MHz IF can be monitored with the help of a
spectrum analyzer using the MIX_OUT SMA (not provid-
Test Points and I/O Connections
Additional test points and I/O connectors are provided
to monitor the various baseband signals and for exter-
nal connections. See Tables 2 and 3 for a description.

notes, visit www.maxim-ic.com.

ed). Remove the ceramic filter for such a measurement
and include R3 (270 ? ) and C17 (0.01μF) to match the
330 ? mixer output with the 50 ? spectrum analyzer.
Jumper JU3 needs to connect pins 1 and 2. It is also
possible to use the MIX_OUT SMA to inject an external
IF as a means of evaluating the baseband data slicing
section. Jumper JU3 needs to connect pins 2 and 3.
F_IN External Frequency Input
For applications where the correct frequency crystal is
not available, it is possible to directly inject an external
frequency through the F_IN SMA (not provided).
Connect the SMA to a function generator. The addition
of C18 and C19 is necessary (use 0.01μF capacitors).
AGC Control
Jumper JU5 controls whether the AGC is enabled.
Connect pins 2 and 3 to enable the AGC. In addition,

locked or unlocked by transitioning the AC pin while the
SHDN pin is high.
Crystal Select
Jumper JU2 controls the crystal-divide ratio.
Connecting pins 1 and 2 sets the divide ratio to 32,
while connecting pins 2 and 3 sets the ratio to 64. This
determines the frequency of the crystal to be used.
Image-Rejection Frequency Select
A unique feature of the MAX7033 is its ability to vary at
which frequency the image rejection is optimized. JU6
allows the selection of three possible frequencies:
315MHz, 375MHz, and 433.92MHz. See Table 1
for settings.
