Quick Start
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.
Test Equipment Required
This section lists the recommended test equipment to
verify operation of the MAX2750/MAX2751/MAX2752. It
is intended as a guide only, and some substitutions are
possible.
• A two-channel power supply at +2.7V to +5.5V
• An ammeter (optional)
• An RF spectrum analyzer (HP 8561E, for example)
that covers the operating frequency range of the
MAX2750/MAX2751/MAX2752, as well as a few har-
monics
• A 50Ω SMA cable
Connections and Setup
This section provides a step-by-step guide to the func-
tions and operation of these EV kits.
1) Connect a DC supply set to +3V (through an amme-
ter, if desired) to the V
CC
and GND terminals on the
EV kit.
2) Apply +3V to the SHDN control input.
3) Turn on the DC supply. The supply current should
read about 10mA.
4) Connect the VCO output to a spectrum analyzer
with a 50Ω coaxial cable (minimize length).
5) Apply a variable DC voltage to the TUNE input
(+0.4V to +2.4V).
6) Check f
MIN
and f
MAX
on the spectrum analyzer by
varying the tuning voltage.
7) Check the output power level (-3dBm typ).
General Description
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.
