1. PRODUCT DESCRIPTION FR01-S4-210
The TRIO mXTENDTM 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 mXTENDTM chip antenna component is capable of operating the main mobile
communication standards, enabling worldwide coverage, such as GSM850, GSM900,
GSM1800/DCS, GSM1900/PCS, UMTS, LTE700, LTE800, LTE850, LTE900, LTE1700,
LTE1800, LTE1900, LTE2000, LTE2100, LTE2300, LTE2500, and LTE2600, (698-960MHz and
1710-2690MHz), the main short range wireless bands such as Bluetooth and Wi-Fi (2400-
2500MHz and 4900-5875MHz), as well as the Global Navigation Systems such as GPS,
Glonass, and Beidou (1561 MHz, 1575 MHz and 1598-1606 MHz) through the same antenna
component. The TRIO mXTENDTM 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 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.

2.2.1. 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 TRIO mXTENDTM chip antenna
component once the design is finished and taking into account all elements of the system
(batteries, displays, covers, etc.).
Figure 2 – Matching network distribution
Please notice that different devices with different ground planes and different components
nearby the TRIO mXTENDTM 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).

5. ASSEMBLY PROCESS
Figure 7 shows the back and front views of the TRIO mXTENDTM chip antenna component
FR01-S4-210. Due to the product configuration, the feeding pad can only be the pad 1.
Figure 7 – Pads of the TRIO mXTENDTM chip antenna component FR01-S4-210.
As a surface mount device (SMD), the TRIO mXTENDTM chip antenna component is compatible
with industry standard soldering processes. The basic assembly procedure for the TRIO
mXTENDTM chip antenna component is as follows:
1. Apply a solder paste on the pads of the PCB. Place the TRIO mXTENDTM chip antenna
component on the board.
2. Perform a reflow process according to the temperature profile detailed in Table 4, Figure 9.
3. After soldering the TRIO mXTENDTM chip antenna component 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:
Figure 8 – 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.
