Quick Start

The MAX2753 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 MAX2753. 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

MAX2753, as well as a few harmonics

•

A 50

Ω SMA cable

•

A 50

Ω SMA termination

•

A 50

Ω balun (optional)

Connections and Setup

This section provides a step-by-step guide to the func-

tions and operation of these EV kits.

1) Connect 50

Ω SMA termination to OUTN.

2) Connect a DC supply set to +3V (through an

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 50

Ω coaxial cable (minimize length). To

measure differential output power, a 50

Ω balun is

required.

6) Apply a variable DC voltage to the TUNE input

(+0.4V to +2.4V).

varying the tuning voltage.

8) Check the output power level (-11dBm typ single-

ended, -8dBm differential).

9) Connect the 50

Ω termination to OUTP

10) Repeat steps 5 through 8.

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.

Features

o Easy Evaluation of MAX2753

o +2.7V to +5.5V Single-Supply Operation
