MAX2622/MAX2623/MAX2624 Evaluation Kits
General Description
Features
ꢀ Easy Evaluation of MAX2622/MAX2623/MAX2624
ꢀ +2.7V to +5.5V Single-Supply Operation
ꢀ RF Output Matched to 50
The MAX2622/MAX2623/MAX2624 evaluation kits
(EV kits) simplify evaluation of the MAX2622/MAX2623/
MAX2624 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 MAX2622,
MAX2623, or MAX2624 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
Quick Start
2) Apply +3V to the SHDN control input.
The MAX2622/MAX2623/MAX2624 EV kits are fully
assembled and factory tested. Follow the instructions in
the Connections and Setup section for proper device
evaluation.
3) Turn on the DC supply. The supply current should
read about 8mA.
4) Connect the VCO output to a spectrum analyzer
with a 50 coaxial cable.
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).
