Quick Start
The MAX2160 EV kit is fully assembled and factory
tested. Follow the instructions in the
Connections and
Setup
section for proper device evaluation.
Test Equipment Required
One power supply capable of supplying at least
500mA, +2.85V
One dual-output power supply capable of supplying at
least 500mA at +3V and -3V
One RF signal generator capable of delivering at least
0dBm of output power at frequencies up to 1GHz
One RF spectrum analyzer capable of covering the
operating frequency range of the device
A PC (486DX33 or better) with Windows 95/98, 2000,
NT 4.0 or later operating system, 64MB of memory,
and an available parallel port
A 25-pin parallel cable
(Optional) One multichannel digital oscilloscope
(Optional) A network analyzer to measure return loss
(Optional) An ammeter to measure supply current

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 sup-
ply to jumpers J15, J17, and J16, respectively. If
available, set the current limits to 50mA.
4) With its output disabled, set the RF signal genera-
tor 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 volt-
ages 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 fre-
quency 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 out-
put 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.
