PCB Layout Requirements
Since this module and its associated set of approved antennas has been certified by the FCC and
Industry Canada (IC) as a Modular Radio, the end user is authorized to integrate this module into an
end-product, and is solely responsible for the Unintentional Emissions levels produced by the endproduct.
In order to preserve the Modular Radio certifications, the integrator of the module must abide by the
PCB layout recommendations outlined in the following paragraphs. Any divergence from these
recommendations will invalidate the modular radio certifications and require the integrator to re-certify
the module and/or end-product.
The module must be used with one of the approved antennas:
1. On module PCB trace antenna.
2. LSR 001-0001 center-fed 2.4 GHz dipole antenna and 080-0001 U.FL to Reverse Polarity SMA
connector cable.
3. LSR 001-0014 2.4 GHz FlexPIFA Antenna.
4. LSR 001-0015 2.4 GHz FlexNotch Antenna.
When using the external antenna version of the module (450-0144), and the reference design that
supports the off module U.FL connector, you may use a substitute antenna if the antenna gain is less
than or equal to +2 dBi.
LSR provides a FCC Modular Certified reference design which utilizes a controlled impedance PCB that
uses microstrip trace design to route the RF signal from the SaBLE-x module to an external coaxial
connector. The external coaxial connector and associated microstrip PCB trace is optional when the
application is using the On Module PCB Trace Antenna version of the module (450-0119).
In order to use the modular certification for your design, it is critical that the reference design is
correctly followed. The full PCB reference design is shown in Figure 4, Schematic Figure 7, and Bill of
Materials Table 10. It is not required to replicate the entire design, but what is required is the circuitry
and layout as it pertains to the antenna configuration as shown in Figure 5 and Figure 6.

6.1
PCB Trace Antenna Implementation
When using the PCB Trace Antenna version of the module (Part Number 450-0119), the PCB layout
shown in Figure 4, Figure 5, and Figure 6 should be followed. It is acceptable to keep the U.FL circuitry
J3, or it may be removed from the PCB to save component cost. By keeping the external U.FL circuitry,
the design can accommodate both antenna versions of the module. To minimize the influence of detuning to the module PCB trace antenna, it is recommended to extend the antenna end of the module
off the edge of the host PCB. Another alternative is to have a cutout notched in the host PCB such that
there is no PCB underneath the antenna end of the module.
6.2
External Antenna Implementation (Dipole, FlexPIFA, or FlexNotch)
When using the External Antenna Port version of the module (Part Number 450-0144), and one of the
three certified 2.4 GHz antennas (Dipole Antenna and U.FL to RPSMA Cable, FlexPIFA, or FlexNotch), the
PCB layout shown in Figure 4 should be followed. The U.FL connector J3 must be populated, and a
controlled impedance microstrip trace ran between the module RF output pad and the U.FL connector
as shown in the Reference Design PCB Figure 4, Figure 5, and Figure 6) and the Schematic Figure 7.
Please use the latest CAD files from the LSR web site when incorporating the SaBLE-x module into a new
design. CAD files are provided in native Mentor Graphics PADS PCB and PADS Logic formats, as well as
ASCII, Gerber, and PDF formats. CAD files can also be translated to most popular CAD package. Contact
LSR Tech support for CAD translation.

Notes for Integrating PCB Trace Antenna Module (450-0119):
1. To minimize the influence of de-tuning to the module PCB trace antenna, it is recommended to
extend the antenna end of the module off the edge of the host PCB.
2. An alternative to cantilevering the antenna outside the edge of the host PCB is to have a cutout
notched in the host PCB, such that there is no PCB underneath the antenna end of the module.
3. The ground plane from the host PCB, and metal of any type, should be kept a minimum of 0.5”
from the antenna circuitry to the left, top, and right of the dashed line shown in Figure 5.
Notes for Integrating External Antenna Module (450-0144):
1. In order to accommodate a design that can support either antenna version of the module, the
designer should follow the notes for integrating a PCB trace antenna from above.

EMC Compliance
7.1
Summary
The SaBLE-x module has been tested and approved as a Modular Radio in accordance with the
appropriate FCC and IC standards. The supporting test data may be found in the modular test report.
Since this module and its associated set of approved antennas have been certified as a Modular Radio,
this allows the end user to integrate this module into an end-product without the requirement of recertifying the radio module. The module-integrator is responsible for the unintentional conducted and
radiated emissions and must verify that the integrated product is compliant with the rules associated
with unintentional radiators. The module integrator is also required to maintain an engineering record
of the verification testing and declare on the product through proper labeling and marking that the
device is compliant with these particular rules. The module integrator is responsible for using the patch
file that corresponds to the antenna configuration and region for EMC compliance.
The installed module’s FCC ID and IC numbers need to be clearly marked on the product with the
following verbiage “Contains FCC ID: TFB-1002” and "Contains IC: 5969A-1002".
The SaBLE-x has been certified for use in a portable configuration, which allows a transmitting device to
be used with any part of its radiating structure in direct contact with the user’s body or within 20 cm of
the body of a user or bystanders under normal operating conditions.
7.2
Module Integration Considerations - Antenna Systems
The module must be used with one of the approved antennas:
1. On module PCB trace antenna.
2. LSR 001-0001 center-fed 2.4 GHz dipole antenna and LSR 080-0001 U.FL to Reverse Polarity SMA
connector cable.
3. LSR 001-0014 2.4 GHz FlexPIFA antenna.
4. LSR 001-0015 2.4 GHz FlexNotch Antenna.
The antenna should be placed such that it is minimally disturbed by the product’s packaging material.
The incorporation of the largest practical free-space clearance around the antenna is important for
maximizing overall performance. Further, the antenna must be placed such that at least a 20 cm
separation distance is maintained from the antenna to all other radio transmitters.
7.3
Module Integration Considerations - Substitute Antenna Systems
The module’s certification is only valid for the list of approved antennas presented in section 4.
However, substitute antennas may be used in place of the approved antenna only if the antennas are of
the same type and the peak gain is less than or equal to the peak gain of the similar approved antenna.
Also the antennas should have similar in-band and out-of-band characteristics.

Application Guide
7.4
Module Integration Considerations - Circuit Implementation
It is recommended that all connection PCB (printed circuit board) traces to the power supply and digital
control terminal be as short as possible. Though not necessarily required in all cases, it is a best practice
to provide an optional shunt capacitor placement at the module pin on all active and routed power
supply and digital control lines. Further, a series damping resistor placement should be incorporated
between the module pin/shunt capacitor node and the source/sink of the digital control signals. This
provides for effective bypassing and decoupling of digital lines from the radio module, in the event that
the application circuit has longer power supply and digital routing.
7.5
Module Integration Considerations - Top Assembly
In addition to the recommendations given for the antenna systems and the module placement onto a
product PCB, it is recommended that all wiring and interconnect systems within the product be not
routed anywhere close the module and its associated circuitry on the PCB, doing so could change the
emission characteristics of the module.
7.6
Testing Requirements for End-Product
Once the module is integrated and the product realized in a mobile or portable configuration, the
product must be tested and follow the verification process for Unintentional Conducted and Radiated
Emissions in accordance to the FCC and IC guidelines. The module needs to be powered and placed in
the receive mode for this test. The receiver must be tuned to its lowest frequency channel, midfrequency channel, and highest frequency channel. The supporting test data does not need to be
submitted to the FCC or IC.
7.7
SAR Testing Requirements for End-Product
Since the SaBLE-x radio module was certified in a portable configuration, the end-product does not
require SAR testing assuming it is not located within 20 cm of another transmitter.
