PRODUCT DESCRIPTION FR01-S4-224 The RUN mXTENDTM Antenna Booster has been specifically designed for providing the major level of flexibility to operate any required frequency band inside any wireless device. The RUN mXTENDTM Antenna Booster is capable of operating the main mobile communication standards, such as GSM850, GSM900, GSM1800/DCS, GSM1900/PCS, UMTS, LTE700, LTE800, LTE850, LTE900, LTE1700, LTE1800, LTE1900, LTE2000, LTE2100, LTE2300, LTE2500, and LTE2600, LTE3500, and LTE3700, through the same antenna component, thus enabling full worldwide 2G, 3G, 4G, and 5G coverage, from 698-960MHz, 1710-2690MHz up to 3400-3800MHz. The RUN mXTENDTM Antenna Booster offers the flexibility to be tuned at the frequency regions of interest through the proper adjustment of the matching network. This characteristic provides an important benefit since removes the need of including different antenna parts inside the same wireless device for operating different communication standards, thus reducing considerably the integration complexity while saving costs. The results gathered herein presents how the matching network should be configured for operating the main mobile communication standards of 2G, 3G, 4G, and 5G.

Additional Last updated on February 2018 (c) 2018 FRACTUS ANTENNAS, S.L. - 4 APPLICATION NOTES information about patents related to http://www.fractusantennas.com/virtual-antenna/. this product is available at Comments: Note that in this case the Evaluation Board (Figure 1) integrates two RUN mXTENDTM Antenna Boosters that are placed together to provide operation at 698-960MHz frequency range. The efficiency measures (Figure 3) are shown from 700 MHz due to the minimum frequency specifications of the Satimo STARGATE 32 anechoic chamber. 2.2.1. MATCHING NETWORKS 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).
