MAX7049 Evaluation Kits
Evaluate: MAX7049
General Description
The MAX7049 evaluation kits (EV kits) provide a proven
design to evaluate the MAX7049 frequency-program-
mable ASK/FSK transmitter in a 28-pin TQFN package
with an exposed pad. The EV kits use Windows XP
®
-,
Windows Vista
®
-, and Windows
®
7-compatible software
to provide a simple graphical user interface (GUI). The
EV kits enable testing of the device’s RF performance
and require no additional support circuitry. The RF out-
put uses a 50I matching network and an SMA connector
for convenient connection to test equipment. The EV kit
PCBs come with a MAX7049ATI+ installed.

DESCRIPTION
Installs the EV kit files on your
computer
Application program
Installs the USB device driver
Uninstalls the EV kit software
USB driver installation help file
stating
ready to use,
then proceed to the next step.
Otherwise, open the USB_Driver_Help_200.PDF
document in the Windows
Start | Programs
menu to
verify that the USB driver was installed successfully.
5)
Start the EV kit software by opening its icon in the
Start | Programs
menu. The EV kit software main
window appears, as shown in Figure 1. The EV kit
GUI indicates if the USB hardware is connected in
the lower-left status bar.
Enter the frequency of the crystal that is in the EV kit
(usually 16MHz) by clicking on the
Options
menu
item and selecting the appropriate frequency.
Connect the RFOUT SMA connector to a power
meter to measure transmitted power, or to a
spectrum analyzer to see the power level and
modulation spectrum. Set the analyzer to a
frequency at or near the center frequency of the
EV kit and set the frequency span to 4MHz. For
example, for an 868MHz EV kit, set the analyzer
center frequency near 868MHz.
The device operates in ASK mode by default.
Set the device carrier frequency to the desired
frequency by typing the frequency in MHz in the
FTX
edit box, and then pressing Enter.
Set the Tx power level by entering an integer
between 0 and 63 in the
ASK Amplitude
edit
box. Each integer represents 0.5mA of DC cur-
rent in the final power amplifier (PA) stage. A
number between 37 and 44 usually produces
a transmitted power level near +13dBm, when
a +3.0V supply voltage is used. For simple
transmission with no data-pulse shaping, leave
the
Pulse
radio button selected in the
Common
Shaping
group box (the default setting).

Procedure
9)
Visit
www.maximintegrated.com/evkitsoftware
to
down-load the latest version of the EV kit software,
7049Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
Install the EV kit software and USB driver on your
computer by running the INSTALL.EXE program
inside the temporary folder. The program files are
copied to your PC and icons are created in the
Windows
Start | Programs
menu. During software
installation, some versions of Windows may show
a warning message indicating that this software
is from an unknown publisher. This is not an error
condition and it is safe to proceed with installation.
Administrator privileges are required to install the
USB device driver on Windows.
Verify that all jumpers are in their default positions,
as shown in Table 1.
Connect the USB cable from the PC to the EV
kit board. A Windows message appears when
connecting the EV kit board to the PC for the
first time. Each version of Windows has a slightly
different message. If you see a Windows message
2)
10) Click on the
MAX7049 Enable
checkbox and verify
that the light is green. Verify that the
TX Ready
light
is also green.
TX Ready
turns green when the
device achieves lock.
11) Click on the
TX Data
checkbox and verify that the
light is green.
12) The spectrum analyzer should display an
unmodulated carrier at 868MHz. The power level
depends on the
ASK Amplitude
setting entered in
Step 9.
13) To test FSK, first uncheck the
MAX7049 Enable
checkbox. Click on the
FSK
radio button in the
Modulation
group box for FSK modulation.
