MAX2307 Evaluation Kit
General Description
The MAX2307 evaluation kit simplifies evaluation of the
MAX2307 integrated RF upconverter-driver. It enables
testing of all functions with no additional support circuit-
ry. Signal inputs and outputs use SMA connectors and
are compatible with the 50Ω impedance of the test
equipment.
Each EV kit is shipped with a Maxim device configured
for operation with an IF input frequency of 165MHz and
LO input frequency of 722MHz to 760MHz. The output-
matching network of each kit is optimized for an RF out-
put frequency of 887MHz to 925MHz.

DESCRIPTION
Capable of supplying +2.8V to 4.2V
at a minimum of 50mA
Or equivalent high-sensitivity
spectrum analyzer
To monitor supply voltage and supply
current (if desired)
For the IFIN and LO inputs or
equivalent sine-wave sources
Connections and Setup
1) Verify the DC power supply is set to less than +4.2V
before attaching the supply to the EV kit. A good
starting voltage is +2.8V.
2) Set V
GC
to +2.2V.
3) Verify the jumpers JU1 and JU2 are in the “V
CC
”
position.
4) The supply current should be approximately 30mA.
5) Connect a signal generator to the IFIN connector
using an SMA cable. Set the generator’s output to
165MHz at -20dBm power level.
6) Connect a second signal generator to the LO input
connector using an SMA cable. Set the generator’s
output to 741MHz at -15dBm power level.
7) Connect the RF output of the EV kit to the spectrum
analyzer using an SMA cable. Take care to use quali-
ty connector adapters for the spectrum analyzer’s
input. Avoid using BNC-type connectors due to their
high VSWR while operating in the gigahertz range.
8) To assist in troubleshooting, verify the correct volt-
ages on the PC board with a multimeter. Use Table 1
to verify correct node voltage during proper opera-
tion.
9) Set the spectrum analyzer’s center frequency to
906MHz.
10) Set the marker position to the peak level.
11) Read the output power of the center frequency. This
should be about +4dBm, depending on cable and
connector losses.
