1 / 2 page  Quick Start 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. Test Equipment Required This section lists the recommended test equipment to verify operation of the MAX2750/MAX2751/MAX2752. 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 MAX2750/MAX2751/MAX2752, as well as a few har- monics • A 50 Ω SMA cable Connections and Setup This section provides a step-by-step guide to the func- tions and operation of these EV kits. 1) Connect a DC supply set to +3V (through an amme- ter, 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 10mA. 4) Connect the VCO output to a spectrum analyzer with a 50 Ω coaxial cable (minimize length). 5) Apply 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). General Description 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.
