MAX2150 Evaluation Kit
Quick Start
The MAX2150 EV kit is fully assembled and factory
tested. 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.
●MAX2150 EV kit
● One RF signal generator capable of delivering -7dBm
of output power in the 10MHz to 50MHz frequency
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)
● PC laptop or tablet with Microsoft Windows XP®,
Windows® 7, 8 OS and a USB port
● USB-A male to USB-B male cable
● US keyboard
Connections and Setup
This section provides step-by-step instructions for getting
the EV kit up and running in all operation modes.
1) Verify that jumpers are in place.
2) Connect the PC to the INTF3000 interface board
using the USB-A male to USB-B male cable. On
INTF3000, remove jumper JU1 and connect a DC
supply set to +3V to the VPULL connector. Connect
a 20-pin ribbon cable between the INTF3000 board
(J3_INTF2300) and the EV kit (J10), keeping the pin
1 to pin 1 connections.
3) Set the power supply to +3V and turn it off.
4) Set the adjustable power supply to +1.6V and turn
it off.
5) Connect the ground terminal to GND.
6) Connect the positive +3V terminal to VCC
and VCCVCO.
7) Connect the positive terminal of the adjustable
power supply to pin DCIN on the board.
8) Set the I/Q generator to 330kHz, with an input level
of 1VP-P. Leave the I/Q generator output off.
9) Using 2 BNC cables, connect the output of the
I/Q generator to the I/Q input connectors on the
MAX2150 EV kit board.
10) Use an SMA cable to connect the RFOUT to the
input of the spectrum analyzer.
11) Set the spectrum analyzer to view the output.
12) Turn on all power supplies and enable I/Q
signal generator.
13) Measure the supply current level.
14) Observe the RF output frequency as displayed on the
spectrum analyzer. Measure the RF output power.
15) The RF output power should be approximately
-4dBm after accounting for cable and connector loss.
Adjustments and Control
Operation Modes
1) TX mode
2) SYNTH mode
3) MOD mode
4) Software shutdown mode
5) Hardware shutdown mode
Refer to the MAX2150 data sheet for details.
Layout Issues
A good PCB is an essential part of an RF circuit
design. The EV kit PCB can serve as a guide for lay-
ing out a board using the MAX2150. Keep traces
carrying RF signals as short as possible to minimize
radiation and insertion loss. Use impedance control on
all RF signal traces. The VCC node on the PCB should
have decoupling capacitors to the closest ground. Refer
to the Layout section of the MAX2150 data sheet for more
information.
