_Quick Start
MAX2673 fully assembled factory tested. Follow instructions Connections Setup section. power supply capable supplying +2.7V +5.5V minimum 50mA
Test Equipment Required
HP8561E spectrum analyzer equivalent high-sensitivity spectrum analyzer Digital multimeters monitor supply voltage supply current, desired HP8648C generators IFIN inputs equivalent sine-wave sources
Connections Setup
Verify power supply less than +5.5V before attaching supply kit. good starting voltage +3.0V. Connect power supply kit, turn power supply Verify SHDN jumper connected VCC, shorted Connect signal generator IFIN connector using cable. with precision connector, care should exercised while threading connector. optimal performance, consult connector manufacturer's specifications torque recommendation. generator's output 70MHz -30dBm power level. Connect second signal generator input connector using cable. generator's output 970MHz -10dBm power level.

Connect output spectrum analyzer using cable. Take care quality connector adapters spectrum analyzer's input. Avoid BNC-type connectors their high VSWR while operating range. assist troubleshooting, verify correct voltages board with multimeter. Table verify correct node voltage during proper operation.
Detailed Description
Figure schematic shipped. output matching components (L1, optimized output frequency 900MHz. Capacitor DC-blocking capacitor input port. reduce possibility noise pickup, resistor capacitor form lowpass filter SHDN pin. Capacitors form decoupling network. Note location each component. Capacitor 10µF tantalum type, located near input test point. This serves central node distribution mixer's supply output pull-up inductor Both these supply points need separate bypass capacitors well separate traces PCB. This prudent practice curtail crosstalk high-frequency systems.

Modifying
MAX2673 easily used output frequencies from 400MHz 2500MHz. operate frequencies other than factory configuration 900MHz, refer Table required component values.
Analysis
spectrum analyzer's center frequency 900MHz, with span 30MHz. marker position peak level. Read output power center frequency. This should nominally -18dBm ±1.3dBm. output frequency equal algebraic difference frequencies. power equal IFIN input power, plus conversion gain upconverter mixer. MAX2673 typical conversion gain 12dB.
