MAX2750/MAX2751/MAX2752 Evaluation Kits

General Description

Features

ꢀ Easy Evaluation of MAX2750/MAX2751/MAX2752

ꢀ +2.7V to +5.5V Single-Supply Operation

ꢀ RF Output Matched to 50

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.

Connections and Setup

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

tions and operation of these EV kits.

NOTE: Please indicate that you are using the MAX2750,

MAX2751, or MAX2752 when contacting these component

suppliers.

1) Connect a DC supply set to +3V (through an amme-

ter, if desired) to the V

EV kit.

and GND terminals on the

2) Apply +3V to the SHDN control input.

Quick Start

3) Turn on the DC supply. The supply current should

read about 10mA.

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.

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

and f

on the spectrum analyzer by

MAX

MIN

varying the tuning voltage.

7) Check the output power level (-3dBm typ).
