MAX2754 Evaluation Kit
General Description
Features
ꢀ Easy Evaluation of MAX2754
The MAX2754 evaluation kit (EV kit) simplifies evalua-
tion of the MAX2754 VCO. This kit enables testing of the
device’s RF performance and requires no additional
support circuitry. The signal output uses an SMA con-
nector to facilitate the connection to RF test equipment.
ꢀ +2.7V to +5.5V Single-Supply Operation

Note: Please indicate that you are using the MAX2754 when
contacting these component suppliers.
8) Check modulation peak frequency deviation on the
spectrum analyzer by varying the modulation volt-
age.
Quick Start
The MAX2754 EV kit is fully assembled and factory test-
ed. Follow the instructions in the Connections and
Setup section for proper device evaluation.
9) Check the output power level (-5dBm typ).
