*If it is difficult to describe this statement on the host product due to the size, please describe in the User's manual. FCC CAUTION Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Compliance with FCC requirement 15.407(c) Data transmission is always initiated by software, which is the passed down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter will be on only while one of the aforementioned packets is being transmitted. In other words, this device automatically discontinue transmission in case of either absence of information to transmit or operational failure. Frequency Tolerance: 20 ppm This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. Copyright Murata Manufacturing Co., Ltd.

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. If the final product with this module is FCC Class B digital device, include the following in the manual of the final product:
Note: 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 LBES5PL2EL (LBEE5PL2DL) module is certied with four external antenna. The external antenna should be connected to the LBES5PL2EL (LBEE5PL2DL) module using 50ohm microstrip RF trace and a U.FL RF connector as shown below. The microstrip RF trace and U.FL connector are placed on the customers PCB and are external to the LBES5PL2EL (LBEE5PL2DL) module. The antenna is then connected to this u.FL Connector via a 50ohm RF adapter cable. The design of the 50ohm microstrip RF trace on the customers PCB is crucially important. Compliant operation of the LBES5PL2EL (LBEE5PL2DL) module is dependent on proper construction of this 50ohm line and the following guidelines must be followed to ensure legal operation of the product. The diagram below shows the required microstrip structure to be routed between module pin 15, 23 and the u.FL connector. The top PCB trace carries the RF energy from module to UFL connector.

The Dielectric material (along with the dimensions of the microstrip structures) determines the characteristic impedance of the microstrip transmission line. Note the representative dimensions shown in the drawing above. It is imperative that the module customer (the integrator) use the exact dimensions we recommend to ensure a 50-ohm impedance for this transmission line. The following dimensions and/or ratios should be used to set the microstrip impedance to 50ohms. Dielectric (PCB) Material We recommend standard FR4 PCB material. Other dielectrics will work but will require recalculation of microstrip dimensions. The following guidance is predicated on the use of FR4 Dielectric. If FR4 is not used for PCB material, please contact Murata to determine new dimensions for microstrip structure. H (Dielectric Height) this is the thickness of dielectric between the trace layer (layer 1) and the ground plane on layer 2. Note that layer 2 must be electrical ground. We recommend a dielectric thickness of 8-15 mils. This range provides the customer with some exibility in board construction. t (trace thickness) Microstrip impedance is not severely affected by the thickness dimension. Standard 102 or 202 copper deposition is recommended. Equivalent thickness is 1-2 mils. W (trace width) this is the crucial dimension. This width must be set correctly to obtain the desired 50 ohms impedance. When using FR-4 dielectric, the width (W) of the microstrip trace should be set to:
