Quick Start
Required Equipment
• MAX7036EVkit
• 3.3V,20mADCpowersupply
• RFgeneratorcapableofdelivering-120dBmto0dBm
output power at the operating frequency, in addition
to amplitude modulation (AM) or pulse modulation
(e.g., Agilent E4420B or equivalent)
• Oscilloscope
• Optionalammeterformeasuringsupplycurrent
Procedure
The MAX7036 EV kit is fully assembled and tested. Follow
the steps below to verify board operation. Caution: Do
not turn on the DC power supply or RF signal genera-
tor until all connections are completed.
1) Verify that the jumpers are in their default position, as
shown in Table 1.
2) Connecta3.3VDCpowersupply(throughanamme-
ter,ifdesired)totheVDDandGNDpadsontheEV
kit.Donotturnonthesupply.
3) Connect the RF signal generator to the P2 SMA con-
nector. Do not turn on the generator output. Set the
generator for an output carrier frequency of 315MHz
(or 433.92MHz) at a power level of -100dBm. Set the
modulation of the generator to provide 100% AM (or
pulse modulation), with a 4kHz square wave.
4) ConnecttheoscilloscopetotestpointTP2(DATAOUT).
5) Turn on the DC power supply. The supply current
should be between 5mA and 6mA.
6) Activate the RF generator’s output without modulation.
Set the RF generator to -100dBm. Enable AM square-
wave (or pulse) modulation on the RF generator and
setthescope’scouplingtoDC.Thescopenowdis-
plays a 4kHz square wave at TP2.
Additional Evaluation
1) With the modulation still set to AM (or pulse), observe
the effect of reducing the RF generator’s amplitude at
TP2 (DATAOUT). The error rate in this sliced digital
signal increases with reduced RF signal level. The
sensitivity is usually defined as the point at which the
error in interpreting the data increases beyond a set
limit, as defined by a bit-error rate (BER) test. Note:
The sensitivity values shown in the MAX7036 IC data
sheet assume that pulse modulation is being used.
Dependingon themodel ofsignal generator,use of
100% AM might not produce identical results to pulse
modulation.
2) Connect the oscilloscope to test point TP1, set the
scope’s coupling to AC, and adjust the voltage sen-
sitivity. The scope now displays a lowpass-filtered
square wave (filtered analog baseband data).
3) Set the scope’s coupling to DC, adjust the voltage
sensitivity, and turn off the modulation from the RF
generator. The scope should display a DC voltage
that varies from approximately 1.35V to 2.2V as the
