TRIO mXTEND™: top triple mobile coverage
- Antenna component: TRIO mXTEND™ NN03-310
- Dimensions: 30.0 mm x 3.0 mm x 1.0 mm
- Frequency regions: 698-960 MHz, 1710-2690 MHz and 3400-3800 MHz

5G goes beyond the connection of people as the industry is now connecting things. The new generation of mobile communication technology goes even further as technology is now connecting everything. 5G has to take on the challenge given by the upcoming wireless market that requires all types of mobile communications standards and a high level of adaptability to many different multiband wireless devices.
The new TRIO mXTEND™ is a modular, multiband and multi-port antenna that has been designed for providing top quality mobile operation at 3G, 4G and 5G in three frequency regions: 698-960 MHz, 1710-2690 MHz and 3400-3800 MHz. This triple mobile coverage of the TRIO mXTEND™ is presented in an ultra slim, off the shelf component of only 1.0 mm height. This enables TRIO mXTEND™ to be assembled into virtually any mobile or IoT device.
TRIO mXTEND™ is fully reconfigurable, being adaptable to any mobile standard requirement thanks to its modular and multi-port nature that allows the operation at 3G, 4G and 5G at the same time and also the possibility of having other operation architectures depending on the service and application needed. The same component is able, for example, to cover 3G, 4G and 5G simultaneously but also to tune only a full top 5G frequency bands coverage.

1. Product description NN03-310
The TRIO mXTEND™ chip antenna component has been specifically designed for providing the major level of flexibility to operate any required frequency band inside any wireless device. TRIO mXTEND™ chip antenna component is capable of operating the main mobile communication standards, enabling worldwide 3G, 4G and 5G coverage, such as GSM850, GSM900, GSM1800/DCS, GSM1900/PCS, UMTS, LTE700, LTE800, LTE850, LTE900, LTE1700, LTE1800, LTE1900, LTE2000, LTE2100, LTE2300, LTE2500, and LTE2600, (698-960 MHz and 1710-2690 MHz) and 5G (3400-3800 MHz), through the same antenna component.
The TRIO mXTEND™ chip antenna component 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 it 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 present how the matching network should be configured for operating the main mobile communication standards of 3G, 4G and 5G.

2.3. Matching network
The specs of an Ignion standard product are measured in their Evaluation Board, which is an ideal case. In a real design, components nearby the antenna, LCDs, 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 TRIO mXTEND™ chip antenna component 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 TRIO mXTEND™ chip antenna component may need a different matching network. To ensure optimal results, the use of high Q and tight tolerance components is highly recommended (Murata components).
