Quick Start Required Equipment Connections and Setup This section provides a step-by-step guide to testing the basic functionality of the EV kits in UHF mode. Caution: Do not turn on DC power or RF signal generators until all connections are completed. • One power supply capable of supplying at least 500mA at +3.3V • One dual-output power supply capable of supplying up to 3V at least 5mA (to apply gain control voltages) 1) Verify that the JP1 and JP6 shunts are removed, the JP2 shunt is installed, and JP11 and JP12 have shunts across pins 1-2. • One RF signal generator capable of delivering at least 0dBm of output power at frequency. (HP 8482A or equivalent) 2) • One RF spectrum analyzer capable of covering the operating frequency range of the device. With its output disabled, set the DC power supply to +3.3V. Connect the power supply to the VCC (through an ammeter if desired) and GND terminals on the EV kits. If available, set the current limit to 500mA. • A PC (486DX33 or better) with Windows® 95/98, 2000, NT 4.0, XP or later operating system, 64MB of memory, and an available parallel port 3) • One 25-pin parallel cable With its output disabled, set both outputs of the dual-output DC power-supply voltages to +3V. Connect one of the outputs to the TP1 connector and the other output to the IF_AGC connector. • 50Ω SMA cables 4) • (Optional) One multichannel digital oscilloscope • (Optional) A network analyzer to measure return loss • (Optional) An ammeter to measure supply current With its output disabled, set the RF signal generator to a 50.5MHz frequency and a -80dBm power level. Connect the output of the RF signal generator to the SMA connector labeled RFIN on the evaluation board. 5) Connect a 25-pin parallel cable between the PC’s parallel port and the MAX3541/MAX3542 evaluation board. 6) Turn on the +3.3V VCC power supply, followed by the +3V dual-output gain-control power supply. The supply current from the +3.3V V CC supply should read approximately 230mA. Be sure to adjust the power supply to account for any voltage drop across the ammeter.

Software is available for download at www.maxim-ic.com/evkitssoftware. 8) Load the default register settings from the control software by clicking Edit: Load Defaults. 9) Connect the SMA connector labeled IF_OUT on the evaluation board to a spectrum analyzer or to an oscilloscope. 10) Enable the RF signal generator’s output. 11) Set the center frequency to the IF frequency set on the control software. Check the output. Gain Adjustment Calculations Add an additional 6dB to the voltage gain to account for the 2:1 transformer on the output. Add another 3.96dB to the voltage gain to account for the minimum loss pad (R10 and R11) on the input. When measuring noise figure, account for 5.7dB power loss of the minimum loss pad. A 36MHz IF anti-aliasing filter is provided on the EV kits (C9, C12, C21, C25, C28, C29, C31, C35, L3, L9, L10, and L11). Anti-aliasing filter requirements vary depending on applications; users should consult their demodulator vendors for more specific information. 4 Layout Considerations The MAX3541/MAX3542 EV kits serve as a guide for PCB layout. Keep RF signal lines as short as possible to minimize losses and radiation. Use controlled impedance on all high-frequency traces. The exposed pad must be soldered evenly to the board’s ground plane for proper operation. Use abundant vias beneath the exposed pad for maximum heat dissipation. Use abundant ground vias between RF traces to minimize undesired coupling. To minimize coupling between different sections of the IC, the ideal power-supply layout is a star configuration, which has a large decoupling capacitor at the central VCC node. The VCC traces branch out from this node, with each trace going to separate V CC pins of the MAX3541/MAX3542. Each VCC pin must have a bypass capacitor with low impedance to ground at the frequency of interest. Do not share ground vias among multiple connections to the PCB ground plane. _______________________________________________________________________________________ IFOUT2+ V CC AGC IFIN- V CC IFIN+ V CC GND IFOUT1- Evaluate: MAX3541/MAX3542 IFOUT1+ MAX3541/MAX3542 Evaluation Kits - V CC V CC V CC AGC V CC V CC V CC Figure 1.
