Quick Start The MAX2753 EV kit is fully assembled and factory tested. 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 2) Connect a DC supply set to +3V (through an ammeter, if desired) to the VCC 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 analyzer 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 fMIN and fMAX on the spectrum analyzer by varying the tuning voltage. 8) Check the output power level (-11dBm typ singleended, -8dBm differential). 9) Connect the 50Ω termination to OUTP 10) Repeat steps 5 through 8. ________________________________________________________________ Maxim Integrated Products 1 For price, delivery, and to place orders, please contact Maxim Distribution at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. Evaluates: MAX2753 General Description The MAX2753 evaluation kit (EV kit) simplifies evaluation 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 connectors to facilitate the connection to RF test equipment.
