19-1897 Rev 0; 1/01 MAX2307 Evaluation Kit The MAX2307 evaluation kit simplifies evaluation of the MAX2307 integrated RF upconverter-driver. It enables testing of all functions with no additional support circuitry. Signal inputs and outputs use SMA connectors and are compatible with the 50Ω impedance of the test equipment. Each EV kit is shipped with a Maxim device configured for operation with an IF input frequency of 165MHz and LO input frequency of 722MHz to 760MHz. The outputmatching network of each kit is optimized for an RF output frequency of 887MHz to 925MHz. Features ♦ +2.8V to +4.2V Single Supply ♦ Output Matched to 50Ω from 887MHz to 925MHz ♦ Differential 400Ω IF Input Matched and Converted to 50Ω Single-Ended for Ease of Lab Testing ♦ Optimal Component Placement ♦ Easy Evaluation of All Product Functions ♦ All Critical Peripheral Components Included Ordering Information PART NUMBER TEMP.

Evaluates: MAX2307 General Description Evaluates: MAX2307 MAX2307 Evaluation Kit Quick Start Each EV kit is fully assembled and factory tested. Follow the instructions in the Connections and Setup section. Test Equipment Required EQUIPMENT DC Power Supply HP 8561E Spectrum Analyzer DESCRIPTION Capable of supplying +2.8V to 4.2V at a minimum of 50mA Or equivalent high-sensitivity spectrum analyzer Digital Multimeters To monitor supply voltage and supply current (if desired) HP 8648C RF Generators, 2 For the IFIN and LO inputs or equivalent sine-wave sources Connections and Setup 1) Verify the DC power supply is set to less than +4.2V before attaching the supply to the EV kit. A good starting voltage is +2.8V. 2) Set VGC to +2.2V. 3) Verify the jumpers JU1 and JU2 are in the “VCC” position. 4) The supply current should be approximately 30mA. 5) Connect a signal generator to the IFIN connector using an SMA cable. Set the generator’s output to 165MHz at -20dBm power level. Table 1. Nominal DC Voltage PIN NUMBER PIN NAME NOMINAL DC VOLTAGE (V) A1 VCC +2.8 A2 VCCMIXP +2.8 A3 VCCMIXM +2.8 A4, C1 GND B1 0 LOIN/SHDNLO +2.8 B3 GC +2.2 B4 RFOUT +2.8 C2 IFINP 0.948 C3 IFINM 0.948 C4 SHDN +2.8 8) To assist in troubleshooting, verify the correct voltages on the PC board with a multimeter. Use Table 1 to verify correct node voltage during proper operation. 9) Set the spectrum analyzer’s center frequency to 906MHz. 10) Set the marker position to the peak level. 11) Read the output power of the center frequency. This should be about +4dBm, depending on cable and connector losses. 6) Connect a second signal generator to the LO input connector using an SMA cable. Set the generator’s output to 741MHz at -15dBm power level. 7) Connect the RF output of the EV kit to the spectrum analyzer using an SMA cable. Take care to use quality connector adapters for the spectrum analyzer’s input. Avoid using BNC-type connectors due to their high VSWR while operating in the gigahertz range.
