7) Enable the low-noise signal generator
’
s output; then
enable the RF signal generator
’
s output.
8) Install and run Maxim
’
s CDMA control software for
the MAX2370 evaluation kit. This software is avail-
able on the web at www.maxim-ic.com/tools/evkit.
On the IC selection form, select 2363-P3. Click on
the Register View button (
Note:
The MAX2363
Register View screen is also used to program the
MAX2370.)
9) With the MAX2363-P3 control screen active, set the
registers according to Table 1. Set the reference
frequency in the control screen to 19.2MHz.
10) Click on the Send Data button for each of the control
registers located at the right of the screen. There
are eight registers that need to be downloaded to
the IC. The Lock indicator on the screen should be
red, indicating that the IF PLL is locked.
11) Apply 2.5V to the VGC header (JU4).
IF Modulator Evaluation
1) Connect the CDMA baseband signal generator to
the I and Q ports using BNC connectors. Set the
modulation to reverse-channel CDMA at an output
level of 780mV
P-P
. The nominal input level at the I/Q
input pins is 130mV
RMS
. Measure the differential
voltage at the chip
’
s I/Q inputs and adjust the signal
generator
’
s output if necessary to achieve
130mV
RMS
.
2) Connect IFOUT to the spectrum analyzer. Configure
the spectrum analyzer to measure ACPR for
reverse-channel CDMA. Set the center frequency to
120MHz with a -10dBm reference level and 30kHz
resolution bandwidth.
3) Adjust the V
GC
voltage until the output power is
-12dBm. The ACPR at ±885kHz offset will be
approximately -66dBc, and the ACPR at ±1.98MHz
will be approximately -84dBc.
