MAX3550/MAX3551/MAX3553 Evaluation Kits
* HP 8648 or equivalent signal source capable of generating 0dBm, up to 900MHz * HP 8561E or equivalent RF spectrum analyzer with minimum frequency range of 100kHz to 3GHz * IBM PC or compatible with Windows (R) 95/98, Windows 2000, Windows NT 4.0, Windows XP, or later operating system and an available parallel port * Male-to-male, 25-pin parallel cable, straight through 7) With the RF signal source output turned off, set the amplitude to -70dBm at 50.25MHz and connect it to RF1 (J12). 8) Connect IF_OUT (J19) to the spectrum analyzer. 9) Turn on the power supplies. 10) Install and run the MAX3550/MAX3551/MAX3553 control software. The control software defaults to standard settings that will be used for the test procedure of this EV kit. The software is available for download on the Maxim website at www.maximic.com/tools/evkit. 11) Under the Options tab, select the proper part type (MAX3550/MAX3551/MAX3553). 12) With the control software active in the Entry screen, select the PIX option in the RF Input section. Default Spectrum Analyzer Settings Reference level = 0dBm Attenuation = 10dB Center frequency = 44MHz (MAX3550/MAX3551) or 36MHz (MAX3553) Span = 10MHz RBW = 100kHz VBW/RBW ratio = 0.03 VBW = 30kHz

Connections and Setup
1) Verify jumpers JP10, JP11, and JP12 are connected to pins 1 and 2. 2) Verify jumpers JP13 and JP14 are connected to pins 2 and 3. 3) To control the MAX3550/MAX3551/MAX3553 through the serial interface, connect the male-tomale, 25-pin parallel cable between the PC's parallel port and EV kit. 4) With the power supply turned off, connect the main power supply (preset to +5.0V) to the header labeled +5V (J14). Connect the main power-supply ground to the header labeled GND (J15). 5) Connect an optional multimeter between +5V (J14) and GND (J15) to monitor the supply voltage. 6) With the power supplies turned off, connect the other two power supplies (preset to +3.0V) to the headers labeled RFAGC (TP7) and IFAGC (TP10). Connect the two power-supply grounds to the ground headers TP8 and TP9.

Gain Adjustment Calculations All input power levels are referenced to RF1 (J12) SMA connector. Be sure to account for power and voltage losses in cables, combiner, minimum loss pad (MLP), and SAW filter. Input minimum loss pad = -5.7dB (Power loss) IF SAW Filter = -14.7dB (44MHz), -20dB (36MHz) (Voltage loss) IF balun = -6dB IF min-loss pad = -5.7dB (Voltage loss) (Power loss, with input MLP total of 11.48dB of voltage loss) Total voltage loss = 11.48 + 14.7 + 6 = 32.18dB (44MHz) Total voltage loss = 11.48 + 20 + 6 = 37.488dB (36MHz) RF Gain and Gain Flatness 1) With the control software active in the Entry screen, enter 50.25MHz into the Frequency box under the RF Input section. 2) Verify VCO lock by selecting Auto Lock Check in the Lock Status section. Green LEDs indicate LOCK. 3) Turn on the output of the signal generator. 4) Set the voltage at both RFAGC and IFAGC to +3.0V. 5) Measure the IF output (P1 in dBm) at IF_OUT at 45.75MHz (MAX3550/MAX3551) or 38.9MHz (MAX3553). 6) Calculate the EV kit gain and active device RF gain by: a) EV kit gain = P1 + 70 (dB) b) Active device RF gain (MAX3550/MAX3551) = P1 + 102.2 (dB) c) Active device RF gain (MAX3553) = P1 + 107.5 (dB) 7) Decrease the IFAGC voltage to +0.5V. 8) Measure the IF output (P1L2 in dBm). 9) Calculate the IF gain-control range by: a) IF gain-control range = P1 - P1L2 (dB) 10) Return the IFVGA voltage back to +3.0V. 11) Decrease the RFVGA voltage to +0.5V. 12) Measure the IF output (P1L in dBm). 13) Calculate the RF gain-control range by: a) RF gain-control range = P1 - P1L (dB) 14) Return the RFVGA voltage back to +3.0V. 15) Change the frequency of the signal generator to 878.25MHz. 16) Enter 878.25MHz into the Frequency box under the RF Input section. 17) Measure the IF output (P2 in dBm). 18) Calculate the RF gain flatness by: a) RF gain flatness = P1 - P2 (dBc) Note: For normal operation, adjust the IFAGC (TP10) voltage to achieve an output amplitude of -9.5dBm at the IF_OUT (J19) SMA connector.
Layout Considerations
The MAX3550/MAX3551/MAX3553 EV kits can serve as guides for board layout. Keep PC board trace lengths as short as possible to minimize parasitics. Also, keep decoupling capacitors as close to the IC as possible with a direct connection to the ground plane.
