Connections and Setup
1) Set the power supply to +2.85V and turn it off.
2) Set the adjustable power supply to +2.0V and turn it off.
3) Connect the ground terminal to GND.
4) Connect the positive +2.85V terminal to VCC,
LO_EN, and
SHDN
two-pin headers.
5) Connect the positive terminal of the adjustable
power supply to GC.
6) Set the IF generator to 380MHz and set the power
level to -11.5dBm at the board IF input. Set the mod-
ulation to WCDMA mode. The IF balun loss and the
board loss, including the 3dB resistive matching loss
due to the on-board 390Ω shunt resistor, account for
about 4.5dB, so the IF power delivered to the
device’s differential LO port is approximately
-16dBm. Keep the RF generator output off.
7) Set the LO generator to 2330MHz and set the
power level to -8dBm. The board loss and the LO
balun loss account for about 2dB, so the LO power
delivered to the device’s differential LO port is
approximately -10dBm. Keep the RF generator out-
put off.
8) Using an SMA cable, connect the output of the IF
generator to the LFIN on the MAX2383 EV kit.
9) Using an SMA cable, connect the output of the LO
generator to the LOIN on the MAX2383 EV kit.
10) Using an SMA cable, connect the DROUT to the
input of the spectrum analyzer.
11) Set the spectrum analyzer to view the output (ACPR
marker, center frequency, etc.).
12) Turn on all power supplies and enable both signal
generators.
13) Observe the RF output frequency as displayed on
the spectrum analyzer. Measure the RF output
power.

Quick Start
Test Equipment Required
• A +3V power supply capable of supplying 50mA.
• An adjustable power supply for gain control.
• An RF signal generator for LO covering the frequen-
cy range of 2270MHz to 2580MHz and output power
range of -15dBm to 0.
• Another RF signal generator for IF with WCDMA mod-
ulation, covering the frequency range of 200MHz to
600MHz, and output power range of
-35dBm to -5dBm.
• A spectrum analyzer with ACPR markers and cover-
ing the frequency range 1900MHz to 2000MHz.

Layout Issues
A good PC board is an essential part of an RF circuit
design. The EV kit PC board can serve as a guide for
laying out a board using the MAX2383. Keep the traces
carrying RF signals as short as possible to minimize
radiation and insertion loss. Use impedance control on
all RF signal traces. The V
CC
node on the PC board
should have decoupling capacitors to the closest
ground. Refer to the
Layout
section of the MAX2383
data sheet for more information.
