Connections and Setup
1)
DC Power Supply:
Set the power-supply voltage to
+5V. Turn the power supply off and connect it to the
VCC and GND connections of the EV kit. If desired,
place an ammeter in series with the power supply to
measure supply current and a voltmeter in parallel
with the VCC and GND connections to measure the
supply voltage delivered to the device.
2)
RF Signal Source:
Set the signal generator to an
RF frequency of 500MHz at an output power level of
-14.3dBm. Turn the output of the signal generator
off. Connect the signal generator to the IN port SMA
connector using a 50鈩?SMA cable. Because the IN
port of the MAX2130 is internally matched to 75鈩?
and the test equipment is a 50鈩?source, an external
matching network converts the load seen by the
signal generator to 50鈩? The power loss of this
impedance-matching network is approximately
5.7dB. The actual power delivered to the IN port of
the MAX2130 is -14.3dBm - 5.7dBm = -20dBm.
3)
Spectrum Analyzer:
Connect the spectrum analyz-
er to the OUT1 port SMA connector using a 50鈩?/div>
SMA cable. Set the center frequency of the spec-
trum analyzer to 500MHz, the span to 1MHz, and
the reference level to 0dBm. Because the MAX2130
is intended to drive a 75鈩?load, a 75鈩?to-50鈩?/div>
impedance-matching network is included between
OUT1 of the MAX2130 and the OUT1 port of the EV
kit. The power loss of this impedance-matching net-
work is approximately 5.7dB.
4)
50鈩?Termination:
Terminate the OUT2 port SMA
connector with a 50鈩?terminator.
Test Equipment Required
This section lists the test equipment required for evalu-
ating the MAX2130:
鈥?One power supply capable of providing 150mA of
supply current at +5V.
鈥?/div>
One HP8648C RF signal generator or equivalent
(50鈩? sine-wave source capable of delivering at
least +10dBm of output power from 44MHz to
878MHz.
One HP8561E RF spectrum analyzer or equivalent
high-sensitivity spectrum analyzer.
Two 50鈩?SMA cables (RG-58A/U or equivalent).
One 50鈩?SMA terminator
Optional: digital multimeters (DMMs) to monitor DC
supply voltage and supply current.
