MAX2753 Evaluation Kit
General Description
The MAX2753 evaluation kit (EV kit) simplifies evalua-
tion of the MAX2753 VCO. This kit enables testing of the
device’s RF performance and requires no additional
support circuitry. The signal outputs use two SMA con-
nectors to facilitate the connection to RF test equip-
ment.
o
Easy Evaluation of MAX2753
o
+2.7V to +5.5V Single-Supply Operation
o
RF Outputs Matched to 50Ω
o
All Critical Peripheral Components Included

Connections and Setup
This section provides a step-by-step guide to the func-
tions and operation of these EV kits.
1) Connect 50Ω SMA termination to OUTN.
2) Connect a DC supply set to +3V (through an
ammeter, if desired) to the V
CC
and GND terminals
on the EV kit.
3) Apply +3V to the
SHDN
control input.
4) Turn on the DC supply. The supply current should
read about 9mA.
5) Connect the VCO output, OUTP, to a spectrum ana-
lyzer with a 50Ω coaxial cable (minimize length). To
measure differential output power, a 50Ω balun is
required.
6) Apply a variable DC voltage to the TUNE input
(+0.4V to +2.4V).
7) Check f
MIN
and f
MAX
on the spectrum analyzer by
varying the tuning voltage.
8) Check the output power level (-11dBm typ single-
ended, -8dBm differential).
9) Connect the 50Ω termination to OUTP
10) Repeat steps 5 through 8.
