Evaluates: MAX2150
Quick Start
The MAX2150 EV kit is fully assembled and factory test-
ed. Follow the instructions in the Connections and
Setup section.
Test Equipment Required
This section lists the recommended test equipment to
verify the operation of the MAX2150. It is intended as a
guide only, and substitutions are possible.
• One RF signal generator capable of delivering
-7dBm of output power in the 10MHz to 50MHz fre-
quency range (HP 8648A or equivalent) for the PLL
reference frequency
• RF spectrum analyzer capable of measuring up to 7GHz
RF signal (Rohde & Schwarz FSEA20 or equivalent)
• RF power meter capable of measuring up to
+10dBm output power (HP 437B or equivalent) with
an RF sensor
• RF network analyzer
• Oscilloscope
• Two power supplies that can provide 250mA at
+5.0V (AG E3631A or equivalent)
• Arbitrary waveform generator (HP E4433B or equivalent)
Connections and Setup
This section provides step-by-step instructions for get-
ting the EV kit up and running in all operation modes.
1) Verify that jumpers are in place.
2) Verify that the interface board is in place.
