MAX2622/MAX2623/MAX2624 Evaluation Kits
General Description
T h e MAX2622/MAX2623/MAX2624 evaluation kits (EV kits) simplify evaluation of the MAX2622/MAX2623/ M A X 2 6 2 4 VCOs. These kits enable testing of the d e v i c e s ' RF performance and require no additional support circuitry. The signal output uses an SMA connector to facilitate the connection to RF test equipment.
Features
o Easy Evaluation of MAX2622/MAX2623/MAX2624 o +2.7V to +5.5V Single-Supply Operation o RF Output Matched to 50 o All Critical Peripheral Components Included

Test Equipment Required
This section lists the recommended test equipment to verify operation of the MAX2622/MAX2623/MAX2624. 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 MAX2622/MAX2623/MAX2624, as well as a few harmonics A 50 SMA cable

Connections and Setup
This section provides a step-by-step guide to the functions and operation of these EV kits. 1) Connect a DC supply set to +3V (through an ammeter, if desired) to the VCC 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 8mA. 4) Connect the VCO output to a spectrum analyzer with a 50 coaxial cable. 5) A p p l y a variable DC voltage to the TUNE input (+0.4V to +2.4V). 6) Check fMIN and fMAX on the spectrum analyzer by varying the tuning voltage. 7) Check the output power level (-3dBm typ).
NOTE: Please indicate that you are using the MAX2622, MAX2623, or MAX2624 when contacting these component suppliers.
Quick Start
T h e MAX2622/MAX2623/MAX2624 EV kits are fully assembled and factory tested. Follow the instructions in the Connections and Setup section for proper device evaluation.
