Last updated on November 2019 (c) 2019 FRACTUS ANTENNAS, S.L. - 5 USER MANUAL RUN mXTENDTM (FR01-S4-224) 3.1. MATCHING NETWORK The specs of a Fractus Antennas standard product are measured in their evaluation board, which is an ideal case. In a real design, components nearby the antenna, LCD's, batteries, covers, connectors, etc. affect the antenna performance. This is the reason why it is highly recommended placing pads compatible with 0402 and 0603 SMD components for a matching network as close as possible to the feeding point. Do it in the ground plane area, not in the clearance area. This provides a degree of freedom to tune the RUN mXTENDTM antenna booster once the design is finished and taking into account all elements of the system (batteries, displays, covers, etc.). Please notice that different devices with different ground planes and different components nearby the RUN mXTENDTM antenna booster may need a different matching network. To ensure optimal results, the use of high Q and tight tolerance components is highly recommended (Murata components). If you need assistance to design your matching network beyond this application note, please contact support@fractusantennas.com, or try our free-ofcharge NN Wireless Fast-Track design service, you will get your chip antenna design including a custom matching network for your device in 24h1.

ASSEMBLY PROCESS Figure 6 shows the back and front view of the RUN mXTENDTM antenna booster FR01-S4-224. Due to the symmetry in the product configuration, the feeding pad can be any of the 2 pads. Mounting Pad (2): solder the RUN mXTENDTM antenna booster mounting pad to the soldering pad on the PCB. This pad must NOT be grounded. 2 1 Feed Pad (1): The 2 pads are fully symmetrical. Once the feeding pad is selected (1), the other pad (2) will become a mounting pad. Align the feed pad with the feeding line on the PCB. See section 5.3. Figure 6 -Pads of the RUN mXTENDTM antenna booster FR01-S4-224. As a surface mount device (SMD), the RUN mXTENDTM antenna booster is compatible with industry standard soldering processes. The basic assembly procedure for the RUN mXTENDTM antenna booster is as follows: 1. Apply a solder paste on the pads of the PCB. Place the RUN mXTENDTM antenna booster on the board. 2. Perform a reflow process according to the temperature profile detailed in Table 4, Figure 8. 3. After soldering the RUN mXTENDTM antenna booster to the circuit board, perform a cleaning process to remove any residual flux. Fractus Antennas recommends conducting a visual inspection after the cleaning process to verify that all reflux has been removed. The drawing below shows the soldering details obtained after a correct assembly process: RUN mXTENDTM antenna booster RUN mXTENDTM antenna booster Solder Paste ~ 0.1* mm PCB PCB Figure 7 - Soldering Details. NOTE(*): Solder paste thickness after the assembly process will depend on the thickness of the soldering stencil mask. A stencil thickness equal or larger than 127 microns (5 mils) is required.
