MAX2750/MAX2751/MAX2752 Evaluation Kits
General Description
Features
ꢀ Easy Evaluation of MAX2750/MAX2751/MAX2752
ꢀ +2.7V to +5.5V Single-Supply Operation
ꢀ RF Output Matched to 50
The MAX2750/MAX2751/MAX2752 evaluation kits
(EV kits) simplify evaluation of the MAX2750/MAX2751/
MAX2752 VCOs. These kits enable testing of the
devices’ RF performance and require no additional
support circuitry. The signal output uses an SMA con-
nector to facilitate the connection to RF test equipment.

Connections and Setup
This section provides a step-by-step guide to the func-
tions and operation of these EV kits.
NOTE: Please indicate that you are using the MAX2750,
MAX2751, or MAX2752 when contacting these component
suppliers.
1) Connect a DC supply set to +3V (through an amme-
ter, if desired) to the V
EV kit.
and GND terminals on the
CC
2) Apply +3V to the SHDN control input.
Quick Start
3) Turn on the DC supply. The supply current should
read about 10mA.
The MAX2750/MAX2751/MAX2752 EV kits are fully
assembled and factory tested. Follow the instructions in
the Connections and Setup section for proper device
evaluation.
4) Connect the VCO output to a spectrum analyzer
with a 50 coaxial cable (minimize length).
5) Apply a variable DC voltage to the TUNE input
(+0.4V to +2.4V).
6) Check f
and f
on the spectrum analyzer by
MAX
MIN
varying the tuning voltage.
7) Check the output power level (-3dBm typ).
