MAX2754 Evaluation Kit
General Description
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.

Test Equipment Required
This section lists the recommended test equipment to
verify operation of the MAX2754. It is intended as a
guide only, and some substitutions are possible.
• Three power supplies 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
MAX2754, as well as a few harmonics
• 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 13.5mA.
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) Apply a variable DC voltage to the MOD input
(+0.4V to +2.4V).
8) Check modulation peak frequency deviation on the
spectrum analyzer by varying the modulation volt-
age.
9) Check the output power level (-5dBm typ).
