MAX2391/MAX2392/MAX2393 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 recommeded test equipment to verify the operation of the MAX2391/MAX2392/ MAX2393 EV kits. It is intended as a guide only, and some substitutions are possible. • DC supply capable of delivering 200mA continuous current at +5.0V • DC supply capable of delivering 200mA continuous current at -5.0V • DC supply capable of delivering 50mA continuous current at +2.8V • HP 34401 or equivalent DMM, to measure IC supply current • HP8648C or equivalent signal source capable of generating -30dBm up to 2.2GHz • HP8561E or equivalent RF spectrum analyzer (baseband spectrum only) • TDS3012 or equivalent digitizing oscilloscope • Windows® 95/98/2000 PC with an available parallel port Connections and Setup This section provides a step-by-step guide to testing the basic functionality of the EV kits. This procedure is specific to the MAX2391 in the UMTS band (reverse channel: 2110MHz to 2170MHz). Adapt the procedure for the MAX2392 or MAX2393 by changing the RF frequency of the test tone to suit the band of interest. The test tone at a 180kHz offset offset works well for all three parts. 1) Install the MAX2391/MAX2392/MAX2393 control software on PC. This software uses a 3rd-party DLL to allow communication through the parallel port: “DriverLINX” by Scientific Software Tools (www.sstnet.com). The Maxim intaller will install this DLL for you automatically. 2) Connect the interface board and cable from the PC parallel port to the EV kit header. Pin 1 on the ribbon cable is indicated with a stripe, and pin 1 on the header is nearest to the corner of the board. The interface board is just populated with logic buffers to protect the parallel port against accidental shorts, but be careful with these connections.

A rough interpolation of the cal factor does not introduce noticable error, if reading the cal factor from a table. 4) Set the signal generator for a 2140.18MHz CW (unmodulated) output at -27dBm, and connect a 3dB pad to the DUT side of the SMA cable. Use the power meter to set the input power to the DUT at -30dBm. Use measured attenuators and/or the signal generator’s internal step attenuators (-40dB) to reduce the signal to -90dBm. Testing the WCDMA Receiver The power-up default state of the MAX2391 receiver is for: • LO midband (2140MHz) • LNA high gain • Mixer high gain, normal linearity • Powered on (out of shutdown) 1) Verify that the IC itself is drawing about 32mA (from VCC_IC). The two MAX4444 differential line drivers at the baseband outputs should draw about 80mA from each of their supplies. 5) Connect the RF source’s SMA cable and attenuators to the EV kit’s LNAIN SMA input. 2) Use the AGC adjust potentiometer on the board to set VAGC at +2.2V (maximum gain). 6) Connect the BNC cable from either I or Q to the spectrum analyzer. Connect the other output into the oscilloscope—be sure to set the oscilloscope’s inputs to 50Ω, and not 1MΩ. Cable loss at 180kHz is neglible; as long as cables are about the same length, no calibration is required at the output to observe proper signal level as well as proper I/Q gain-and-phase balance. 3) Spot-check the VCO tuning voltage (TUNE) to see that the synthesizer is locked. The voltage should be about mid-supply with the RFLO running at its power-up default of 2140MHz. Disconnect any leads from this before continuing, as the noise pickup onto the tuning line directly frequency-modulates the VCO, and degrades LO phase noise. 7) Set one of the DC supplies to 2.8V and set a current limit of 100mA (if available). Connect this supply through the ammeter to “VCC_IC”, and readjust the supply if necessary to get 2.8V at the IC when powered up. This supply connection only powers the IC on the EV kit – read the ammeter to watch IC supply current for the receiver. Connect another line directly from the 2.8V supply to “VCC_EXT” to supply the external logic on the kit. Not having the voltage drop of the ammeter inline means the voltage is slightly higher than VCC_IC, but this does not cause a problem. 8) Set the other supplies for ±5.0V with a current limit of about 100mA. Connect these supplies to the +5V, GND, and -5V on the opposite side of the kit. These are the bipolar supplies for the MAX4444 differential line drivers that buffer the I/Q outputs. Note that all GND test points are connected to the same ground plane—it is only necessary to use one of them. 8) Set the spectrum analyzer to span from DC (minimum sweep) to 2MHz. Set the reference level to +10dBm. 9) Set the oscilloscope for a sweep rate of about 1µs/div, DC coupling, with an amplitude scale of about 100mV/div. 6 4) Observe the 180kHz tone on the spectrum analyzer. Adjust AGC to to achieve a -3.5dBm output level. 5) The on-board TCXO has a fine-tuning control—the other potentiometer on the EV kit allows for external temperature compensation of the TCXO to further decrease frequency error. Adjust the TCXO potentiometer if desired to bring the output tone exactly to 180kHz. 6) Observe the other output on the oscilloscope. At these input power levels, the SNR is typically much too low to see the output tone through the noise. If available, use the internal low pass filter option (often 20MHz) and lots of averaging. 7) To make a gain/phase error measurement, connect both outputs to the scope. Increase the input power to about -50dBm, and back off the AGC until the outputs are swinging about 0.42VP-P. Again, use digital averaging to get both I and Q sinusoids visible on the scope. If automated measurements for phase and amplitude are not available, use the cursors to make the measurement. Calculate phase error in degrees, and gain error in dB, and verify that the results are better than 2 degrees and 0.6dB, respectively. _______________________________________________________________________________________ MAX2391/MAX2392/MAX2393 Evaluation Kit Evaluate: MAX2391/2/3 Figure 1a.
