Schematic
A schematic diagram of the module is shown in
Figure 2-1 and the Bill of Materials (BOM) is shown in
Table 2-1.
The MRF24J40MA module is based on the Microchip
Technology MRF24J40 IEEE 802.15.4™ 2.4 GHz RF
Transceiver IC. The serial I/O (SCK, SDI, SDO and
CS), RESET, WAKE, INT and CLKOUT pins are
brought out to the module pins. The SDO signal is
tri-state buffered by IC2 to solve a silicon errata where
the SDO signal does not release to a high-impedance
state after the CS pin returns to its inactive state.
Crystal X1 is a 20 MHz crystal with a frequency
tolerance of ±20 ppm @ 25°C to meet the IEEE Std.
802.15.4 symbol rate tolerance of ±40 ppm. A balun is
formed by components: L1, L3, C2 and C14. L2 is an
RF choke and pull-up for the RFP and RFN pins on the
MRF24J40. C15 is a DC block capacitor. A low-pass
filter is formed by components: L4, C16 and C17. The
remaining capacitors provide RF and digital bypass.

The Printed Circuit Board (PCB) antenna was designed
and simulated using Ansoft Designer® and HFSS™ 3D
full-wave solver software by Ansoft Corporation
(www.ansoft.com). The design goal was to create a
compact, low-cost antenna with the best radiation
pattern. Figure 2-9 shows the simulation drawing and
Figure 2-10 and Figure 2-11 show the 2D and 3D
radiation patterns, respectively. As shown by the
radiation patterns, the performance of the antenna is
dependant upon the orientation of the module.
Figure 2-12 shows the impedance simulation and
Figure 2-13 shows the actual impedance measurement.
The discrete matching circuitry matches the impedance
of the antenna with the MRF24J40 transceiver IC.

REGULATORY APPROVAL
The MRF24J40MA module has received regulatory
approvals for modular devices in the United States,
Canada and European countries. Modular approval
allows the end user to place the MRF24J40MA module
inside a finished product and not require regulatory
testing for an intentional radiator (RF transmitter), provided no changes or modifications are made to the
module circuitry. Changes or modifications could void
the user’s authority to operate the equipment. The end
user must comply with all of the instructions provided
by the Grantee, which indicate installation and/or
operating conditions necessary for compliance.
The integrator may still be responsible for testing the end
product for any additional compliance requirements
required with this module installed (for example: digital
device emission, PC peripheral requirements, etc.) in

3.1
United States
The user’s manual should include the following
statement:
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful
interference in a residential installation. This
equipment generates, uses and can radiate radio
frequency energy, and if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However, there
is no guarantee that interference will not occur in a
particular installation. If this equipment does cause
harmful interference to radio or television reception,
which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment
and receiver.
• Connect the equipment into an outlet on a
circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV
technician for help.
3.1.1
The MRF24J40MA has received Federal Communications Commission (FCC) CFR47 Telecommunications,
Part 15 Subpart C “Intentional Radiators” 15.247 and
modular approval in accordance with FCC Public
Notice DA 00-1407 Released: June 26, 2000, Part 15
Unlicensed Modular Transmitter Approval. The
MRF24J40MA module can be integrated into a finished
product without obtaining subsequent and separate
FCC approvals.
The MRF24J40MA module has been labeled with its
own FCC ID number, and if the FCC ID is not visible
when the module is installed inside another device,
then the outside of the finished product into which the
module is installed must also display a label referring to
the enclosed module. This exterior label can use
wording such as the following:
RF EXPOSURE
All transmitters regulated by FCC must comply with RF
exposure requirements. OET Bulletin 65 “Evaluating
Compliance with FCC Guidelines for Human Exposure
to Radio Frequency Electromagnetic Fields” provides
assistance in determining whether proposed or existing
transmitting facilities, operations or devices comply
with limits for human exposure to Radio Frequency
(RF) fields adopted by the Federal Communications
Commission (FCC). The bulletin offers guidelines and
suggestions for evaluating compliance.
If appropriate, compliance with exposure guidelines for
mobile and unlicensed devices can be accomplished
by the use of warning labels and by providing users
with information concerning minimum separation
distances from transmitting structures and proper
installation of antennas.

MRF24J40MA
The following statement must be included as a
CAUTION statement in manuals and OEM products to
alert users of FCC RF Exposure compliance:
To satisfy FCC RF Exposure requirements for mobile
and base station transmission devices, a separation
distance of 20 cm or more should be maintained
between the antenna of this device and persons
during operation. To ensure compliance, operation at
closer than this distance is not recommended.
The antenna(s) used for this transmitter must not be
co-located or operating in conjunction with any other
antenna or transmitter.
From section 5.2, RSS-Gen, Issue 2, June 2007,
Equipment Labels:
All Category I radio equipment intended for use in
Canada shall permanently display on each transmitter,
receiver, or inseparable combination thereof, the
applicant’s name (i.e., manufacturer’s name, trade
name or brand name), model number and certification
number. This information shall be affixed in such a
manner as to not be removable except by destruction or
defacement. The size of the lettering shall be legible
without the aid of magnification, but is not required to be
larger than 8-point font size. If the device is too small to
meet this condition, the information can be included in
the user manual upon agreement with Industry Canada.
If the MRF24J40MA module is used in a portable
application (antenna is less than 20 cm from persons
during operation), the integrator is responsible for
performing Specific Absorption Rate (SAR) testing in
accordance with FCC rules 2.1091.
Label:
3.1.2
If the device contains digital circuitry that is not directly
associated with the radio transmitter, the device shall
also have to comply with ICES-003, Class A or B as
appropriate,
except
for
ICES-003
labeling
requirements. The test data obtained (for the ICES-003
tests) shall be kept by the manufacturer or importer
whose name appears on the equipment label, and
made available to Industry Canada on request, for as
long as the model is being marketed in Canada.
