♦ +2.7V to +5.5V Single Supply
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.
♦ Output Matched for 50Ω at 900MHz
♦ Optimal Component Placement
♦ Easy Evaluation of All Product Functions
♦ Includes All Critical Peripheral Components
Each EV kit is shipped with a MAX2673 configured for
op e ra tion with a n IF inp ut fre q ue nc y of 40MHz to
500MHz, a nd LO inp ut fre q ue nc y of 600MHz to
2400MHz. The output matching network is optimized for
an RF output frequency of 900MHz.

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.

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
re c omme nd a tion. Se t the g e ne ra tor’s outp ut to
70MHz at -30dBm power level.
