MAX2673 Evaluation Kit
General Description
The MAX2673 evaluation kit (EV kit) simplifies evalua-
tion of the MAX2673 upconverter mixer and enables
testing of all functions, with no additional support cir-
cuitry. Signal inputs and outputs use SMA connectors
and are compatible with the 50Ω impedance of test
equipment.
Each EV kit is shipped with a MAX2673 configured for
operation with an IF input frequency of 40MHz to
500MHz, and LO input frequency of 600MHz to
2400MHz. The output matching network is optimized for
an RF output frequency of 900MHz.

_________________________Quick Start
The MAX2673 EV kit is fully assembled and factory test-
ed. Follow the instructions in the Connections and
Setup section.
Test Equipment Required
• DC power supply capable of supplying +2.7V to
+5.5V at a minimum of 50mA
• HP8561E spectrum analyzer or equivalent high-sen-
sitivity spectrum analyzer
• Digital multimeters to monitor supply voltage and
supply current, if desired
• Two HP8648C RF generators for the IFIN and LO
inputs or equivalent sine-wave sources
Connections and Setup
• Verify the DC power supply is set to less than +5.5V
before attaching the supply to the EV kit. A good
starting voltage is +3.0V. Connect the power supply
to the EV kit, and turn the power supply on.
2) Verify the SHDN jumper is connected to V_CC, pin 1
shorted to pin 2.
3) Connect a signal generator to the IFIN connector
using an SMA cable. As with any precision RF con-
nector, care should be exercised while threading
the connector. For optimal performance, consult the
connector manufacturer’s specifications for torque
recommendation. Set the generator’s output to
70MHz at -30dBm power level.
4) Connect a second signal generator to the LO input
connector using an SMA cable. Set the generator’s
output to 970MHz at -10dBm power level.
