The MRF24J40MA module operates in the non-licensed 2.4 GHz frequency band and is FCC, IC and ETSI compliant. The integrated module design frees the integrator from extensive RF and antenna design, and regulatory compliance testing, allowing quicker time to market. The MRF24J40MA module is compatible with Microchip's ZigBee(R), MiWiTM and MiWi P2P software stacks. Each software stack is available as a free download, including source code, from the Microchip web site http://www.microchip.com/wireless. The MRF24J40MA module has received regulatory approvals for modular devices in the United States (FCC), Canada (IC) and Europe (ETSI). Modular approval removes the need for expensive RF and antenna design and allows the end user to place the MRF24J40MA module inside a finished product and not require regulatory testing for an intentional radiator (RF transmitter). See Section 3.0 "Regulatory Approval" for specific requirements to be followed by the integrator. 1.1 Interface Description Figure 1-1 shows a simplified block diagram of the MRF24J40MA module. The module is based on the Microchip Technology MRF24J40 IEEE 802.15.4TM 2.4 GHz RF Transceiver chip. The module interfaces to many popular Microchip PIC(R) microcontrollers via a 4-wire serial SPI interface, interrupt, wake, Reset, power and ground as shown in Figure 1-2. Table 1-1 provides the pin descriptions. Data communications with the MRF24J40MA module are documented in the "MRF24J40 IEEE 802.15.4TM 2.4 GHz RF Transceiver Data Sheet" (DS39776).

The layers below the antenna have no copper traces. The ground and power planes under the components serve as a counterpoise to the PCB antenna. Additional ground plane on the host PCB will substantially enhance the performance of the module. For best performance, place the module on the host PCB following the recommendations in Section 1.2 "Mounting Details". The Printed Circuit Board (PCB) antenna was designed and simulated using Ansoft Designer(R) and HFSSTM 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.

MRF24J40MA 3.0 REGULATORY APPROVAL 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. 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 the specific country that the end device will be marketed. Annex F of the IEEE Std. 802.15.4 document has a good summary of regulatory requirements in various countries concerning IEEE Std. 802.15.4 devices. The standard can be downloaded from the IEEE Standards web page: http://standards.ieee.org/getieee802/802.15.html. Refer to the specific country radio regulations for details on regulatory compliance. 3.1 United States 3.1.1 RF EXPOSURE 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: Contains Transmitter Module FCC ID: OA3MRF24J40MA -orContains FCC ID: OA3MRF24J40MA This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 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.
