Connections and Setup
This section provides a step-by-step guide to testing the basic functionality of the EV kit. Do not turn on DC power or RF signal generators until all connections are completed: 1) Verify that all the desired jumpers are in place (see Table 1). 2) With its output disabled, set the DC power supply to +2.85V. Connect the power supply to the VCC (through an ammeter if desired) and GND terminals on the EV kit. If available, set the current limit to 75mA. 3) With its output disabled, set the dual-output DC power-supply voltages to +3V and -3V. Connect the +3V, -3V, and GND terminals of the power supply to jumpers J15, J17, and J16, respectively. If available, set the current limits to 50mA. 4) With its output disabled, set the RF signal generator to a 767.143MHz frequency and a -60dBm power level. Connect the output of the RF signal generator to J5 on the evaluation board. 5) Connect a 25-pin parallel cable between the PC's parallel port and the MAX2160 evaluation board. 6) Turn on the 3V power supply, followed by the +2.85V power supply. The supply current from the +2.85V supply should read approximately 44mA. Be sure to adjust the power supply to account for any voltage drop across the ammeter. 7) Adjust potentiometers R16 and R17 until the voltages at GC1 and GC2 are approximately 1.5V. 8) Install and run the MAX2160 control software. Software is available for download on the Maxim website at www.maxim-ic.com. 9) Load the default register settings from the control software by clicking the Defaults tab at the top of the screen. 10) Connect either the I or Q output to the spectrum analyzer, or connect both I and Q outputs to the oscilloscope. 11) Enable the RF signal generator's output. 12) If using a spectrum analyzer, set the center frequency of the analyzer to 571kHz and a span of 100kHz. Set the reference level to 0dBm. Increase the input power of the signal generator until the output level reaches -2dBm. This is the nominal output level for the I and Q channels. The gain of the receiver can be calculated by taking the difference in dB between the input and output power.

MAX2160 Evaluation Kit
If using an oscilloscope, observe the 571kHz sine wave. Increase the input power of the signal generator until the I and Q outputs reach 0.5VP-P. This is the nominal output level for the I and Q channels. The I and Q waveforms will be out-of-phase by approximately 90. Voltage gain can be calculated by: Gain = 20 x LOG(VOUT_P-P / (2 x sqrt(2) x VIN_RMS) ) where VIN_RMS = ( 50 x 10[ (Pin (dBm) - 30) / 10] ) RF Gain-Control Range (GC1) To measure the gain-control range in the RF stage, follow the steps below: 1) Adjust R17 so VGC2 = 1.5V. 2) Adjust R16 so VGC1 = 0.3V. 3) Adjust the RF input power to achieve -2dBm at the I/Q outputs. Record this as the reference output level. 4) Adjust R16 until V GC1 = 2.7V, and record the change in the I/Q output levels in dB relative to -2dBm. This change in output power is the gaincontrol range of the RF stage. 5) The RF gain-control range will be at least 38dB. Baseband Gain-Control Range (GC2) To measure the gain-control range in the baseband stage, follow the steps below: 1) Adjust R16 so VGC1 = 1.5V. 2) Adjust R17 so VGC2 = 0.3V. 3) Adjust the RF input power to achieve -2dBm at the I/Q outputs. Record this as the reference output level. 4) Adjust R17 until VGC2 = 2.7V, and record the change in the I/Q output levels in dB relative to -2dBm. This change in output power is the gain-control range of the baseband stage. 5) The baseband gain-control range will be at least 57dB.
J7
In addition, the ground returns for the VCO, VTUNE, and charge pump require special layout consideration. The VCOBYP capacitor (C37) and the VCCVCO bypass capacitor (C19) ground returns must be routed back to the GNDVCO pin and then connected to the overall ground plane at that point (GNDVCO). All loop filter component grounds (C27-C30) and the VCCCP bypass capacitor (C17) ground must all be routed together back to the GNDCP pin. GNDTUNE must also be routed back to the GNDCP pin along with all other grounds from the PLL loop filter. The GNDCP pin must then be connected to the overall ground plane. See Figures 2-6 for recommended board layout.

Layout Considerations
The MAX2160 evaluation board can serve as a reference board layout. Keep traces carrying RF signals as short as possible to minimize radiation and insertion loss. Place supply-decoupling capacitors as close to the device as possible. Solder the package's exposed paddle evenly to the board ground plane for a low-inductance ground connection and for improved thermal dissipation.
