3. Customer PCB Design Guide
3. 1 Customer PCB PAD Design Guide
With reference to the following Figure 3. 1 Design Guide, please design the customer's PCB.
[Top View]
Figure 3. 1 Cusomer PCB Layout Guide
WISOL Confidential © 2016 WISOL CO.,LTD. All Rights Reserved 23
3. 2 Installation Guidelines for Antenna PAD
The proper connection between the antenna pad and the application PCB
must be implementing the following installation guidelines for the layout of the application PCB.
a) The whole layer stack below the antenna connection pad should be free of digital lines.
b) Increase GND keep-out (i.e. clearance) around the antenna pad, on the top layer of the
application PCB, to at least 150 µm up to adjacent pads metal definition on the area below the
module, to reduce parasitic capacitance to ground.
c) Add GND clearance on the buried metal layer below the antenna pad,
to reduce parasitic capacitance to ground.
Figure 3. 2 GND clearance on top layer around antenna pad
Figure 3. 3 On the 2nd buried layer below antenna pad
When you intend to install this module(LTM100) with RF connector type,
please refer to the trace guideline figure below. (trace loss: max. 0.3dB)
Figure 3. 4 Trace guideline from the antenna pad to the RF connector pad
WISOL Confidential © 2016 WISOL CO.,LTD. All Rights Reserved 24
3. 3 Antenna line Guidelines
a) Make sure that the impedance of the microstrip line is 50ohm.
b) Reduce the return loss(or V.S.W.R.) as possible with the help of antenna designers.
c) Avoid having other signal tracks and crossing any un-shielded transmission line footprint
with other signal tracks on different layers.
d) The ground surrounding the antenna line should be directly connected to the main ground
plane on the PCB by means of via holes.
e) Place EM noisy devices far away from the antenna line as possible.
f) Keep the antenna line far away from the power supply lines.
4. FCC Warnings and Notices
4. 1 FCC Warnings
The FCC requires the user to be notified that any changes or modifications made to this
module that are not expressly approved by WISOL CO., LTD could void the user's authority
to operate the equipment.
4. 2 Notices
a) If not installed and used in accordance with the instructions on the manual,
this module may cause a malfunction.
In designing this module, please follow the instructions in this manual.
b) Final Installers should be require to satisfy RF exposure compliance for installations and final
host devices.
Compliance of this device in all final host configurations is the responsibility of the guarantee.
The maximum permitted antenna gain including cable loss of the final host device is as follows.

following information in a prominent location.
“To comply with FCC RF exposure compliance requirements, the antenna used for this
transmitter must be installed to provide a separation distance of at least 20 cm from all
persons and must not be co-located or operating in conjunction with any other antenna
or transmitter.
c) If the FCC ID is not visible when this module(LTM100) is installed inside final host device,
then a label must be affixed to the outside of the final host device with a statement similar
to the following:
"Contains FCC ID: 2ABA2LTM100" or “This device contains FCC ID: 2ABA2LTM100”
