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.
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 50
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 50
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).
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.
Features
o Easy Evaluation of MAX2754
o +2.7V to +5.5V Single-Supply Operation
o RF Output Matched to 50
o All Critical Peripheral Components Included
