Comments:
Note that in the Evaluation Boards (Figure 1), 2 CUBE mXTENDTM Antenna Boosters
are placed together to provide operation at LTE700 (698 – 798 MHz). Please see Figure
29 for the recommended footprint.
The efficiency measures (Figure 3 and Figure 4) are shown from 700 MHz due to the
minimum frequency specifications of the Satimo STARGATE 32 anechoic chamber.
Please contact info@fractusantennas.com for more information related to the Antenna
Booster matching service.
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 CUBE mXTENDTM Antenna
Booster once the design is finished and taking into account all elements of the system.
Please notice that different devices with different ground planes and components nearby the
CUBE 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).

5.2.1. 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 CUBE mXTENDTM Antenna
Booster once the design is finished and taking into account all elements of the system.
Please notice that different devices with different ground planes and components nearby the
CUBE mXTENDTM Antenna Booster may need a different matching network. To ensure optimal

Comments:
Note that in the Evaluation Boards (Figure 19 and Figure 23), 2 CUBE mXTENDTM
Antenna Boosters are placed together to provide operation at LTE700 (698 – 798 MHz).
Please see Figure 29 for the recommended footprint.
The efficiency measures (Figure 21 and Figure 25) are shown from 700 MHz due to the
minimum frequency specifications of the Satimo STARGATE 32 anechoic chamber.
Note that for obtaining comparable results, a ground plane length larger than 100 mm is
recommended.

6.3.1. 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 CUBE mXTENDTM Antenna
Booster once the design is finished and taking into account all elements of the system.
Please notice that different devices with different ground planes and components nearby the
CUBE 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).

9. ASSEMBLY PROCESS
Figure 30 shows the back and front view of the CUBE mXTENDTM Antenna Booster FR01-S4-
250. Due to the symmetry in the product configuration, the feeding pad can be any of the 4
pads.
Figure 30 – Pads of the CUBE mXTENDTM Antenna Booster FR01-S4-250.
As a surface mount device (SMD), the CUBE mXTENDTM Antenna Booster is compatible with
industry standard soldering processes. The basic assembly procedure for the CUBE
mXTENDTM Antenna Booster is as follows:
1. Apply a solder paste on the pads of the PCB. Place the CUBE mXTENDTM Antenna Booster
on the board.
2. Perform a reflow process according to the temperature profile detailed in Table 23, Figure 32
(page 50).
3. After soldering the CUBE 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:
Figure 31 – Soldering Details.

Mounting Pads (2, 3, 4): solder the CUBE mXTENDTM Antenna Booster mounting
pads to the soldering pads on the PCB. These pads must NOT be grounded.
Feed Pad (1): The 4 pads are fully symmetrical. Once the feeding pad is selected (1), the other 3 pads
become mounting pads. Align the feed pad with the feeding line on the PCB. See section 0.

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.
