MAX4146x Evaluation Kit
Evaluates: MAX41463
MAX41464
General Description
The MAX4146x evaluation kit (EV kit) contains a single
MAX4146x high output power VHF/UHF sub-GHz ISM/
SRD transmitter, designed to transmit Frequency-Shift
Keying (FSK), Gaussian GFSK or Amplitude-Shift Keying
(ASK) data in the 286MHz to 960MHz frequency range.
The MAX41460 and the MAX41461–MAX41464
evaluation kits operate in conjunction with an external
microcontroller (MCU) and Graphical User Interface (GUI)
software running on a computer. The MAX41460 uses an
SPI interface for internal register configurations while the
MAX41461–MAX41464 can use the preset modes or an
I
2
C interface for register programming and control.
The MAX41461, MAX41462, MAX41463, and MAX41464
evaluation kits are also designed to operate with a simple,
one-pin data interface, alleviating the need to program the
part for nominal operation, or other high-level system (PC
with GUI software) having to configure the transmitter for
operation. These parts allow the user to preset the operating
frequencies by part selection and pin configurations. On
the evaluation kit, selecting the frequency of operation is
as simple as setting two jumpers.
The EV kit includes Windows
®
7/10-compatible software
that provides a simple graphical user interface (GUI)
for configuration of all the MAX4146x registers through
the SPI or I
2
C ports. The GUI also controls the on-
board PMIC and can act as a data generator, when the
MAX32630FTHR Applications Platform is used.

EV kit will be preprogrammed for interfacing the GUI
to the radio. The firmware programming process does
not require additional software or drivers, it uses a
simple USB drive, drag-and-drop file interface.
It is highly recommended that the target PC be connected
to a local area network and have access to the Internet,
this allows for automatic download and updates of some
drivers. This process may take 15 minutes or more to
complete.

needed once, when configuring the hardware and the
PC for the first time. If these steps have already been
completed, jump directly to the
FTHR Board Quick Start
Procedure.
Install the MAX4146x EV Kit GUI Software
Software and Drivers
This process should take less than 10 minutes after
downloading the software package.
Refer to
Appendix I
for detailed information on this installation process.

2)
3)
Copy the “Setup
MAX4146X V1.0.0 EVKit SW.rar”
file to a working folder on the target PC.
Extract the setup file contents into the working
directory.
Double-Click the “MAX4146xGUISetupV01.msi”

window.
in the MAX4146X Setup Wizard
The MAX4146x EV kit can be used in conjunction with
the ARM Cortex-M4F microcontroller MAX32630FTHR
Application Platform or “FTHR” board to provide power
and control the device through a software application or
Graphical User Interface (GUI). For this option, additional
equipment is required:
When connected to the FTHR board the MAX4146x EV
kit uses the following drivers and software components.
Refer to the
Appendix I
for additional information on this
installation process.

1.
Update the MAX32630FTHR Board Driver
on the Host PC
No changes are needed for the FTHR board when first
receiving a MAX4146x EV kit—the FTHR board has been
pre-loaded with the required firmware. Updates to the
driver on the host PC may be necessary depending on the
operating system and whether the PC has access to the
internet when first connecting to the FTHR board.
Refer to
Appendix I
for detailed information on how to update the
FTHR board firmware and the driver for the FTHR board/
USB interface.
Setup the MAX4146x EV kit and FTHR Board Hardware
MCU/GUI Operation.
Verify all jumpers on the MAX4146x EV kit board
are in the default position;
refer to
Table 2.
a. For the MAX41460 EV kit, JU2, JU3 and JU5
should not be installed.
b. For MAX41461-MAX41464 EV kits, JU2 and JU3
must be installed 2-3 (SEL0 and SEL1 connected
to GND); JU5 must be installed with jumpers from
pins 1-2 and 3-4.
2.
Connect the MAX4146x EV kit to the FTHR board,
be sure the USB connector is oriented on the opposite
side of the SMA connector, as shown in
Figure 3.
