Sterling-LWB User Manual Copyright 2016 LSR Page 22 of 30 Sterling-LWB Module APPLICATION GUIDE 6 EMC Compliance 6.1 Summary The Sterling-LWB 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 re-

certifying 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 installed modules FCC ID and IC numbers need to be clearly marked on the product with the following verbiage Contains FCC ID: TFB-1003 and "Contains IC: 5969A-1003". 6.2 Module Integration Considerations - Antenna Systems The module must be used with one of the approved antennas:

1) LSR 001-0001 2.4 GHz center-fed dipole antenna and LSR 080-0001 U.FL to Reverse Polarity SMA connector cable. 2) LSR 001-0014 2.4 GHz FlexPIFA antenna. 3) LSR 001-0015 2.4 GHz FlexNotch antenna. Johanson 2450AT18D0100 chip antenna. 4) The antenna should be placed such that it is minimally disturbed by the products 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. 6.3 Module Integration Considerations - Substitute Antenna Systems The modules certification is only valid for the list of approved antennas presented in section 5. When using the U.FL connector, you may use a substitute antenna if the peak antenna gain is to equal or less than +2 dBi. It may be possible to use a substitute chip antenna however there are restrictions so please contact LSR for guidance prior to making any chip antenna substitutions. The information in this document is subject to change without notice. Sterling-LWB User Manual Copyright 2016 LSR Page 23 of 30 Sterling-LWB Module APPLICATION GUIDE 6.4 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. 6.5 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 not be routed anywhere close the module and its associated circuitry on the PCB, doing so could change the emission characteristics of the module. 6.6 Testing Requirements for End-Product Once the module is integrated and the end-product is realized, the end-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, mid-frequency channel, and highest frequency channel. The supporting test data does not need to be submitted to the FCC or IC. The implementation of the module in a specific end-product should also be reviewed to ensure compliance with the FCC and IC requirements for SAR and MPE. Additional information for SAR requirements of this module can be found in this document. The information in this document is subject to change without notice.

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. Johanson Technology 2450AT18D0100 Ceramic Chip Antenna. 2. LSR 001-0014 2.4 GHz FlexPIFA Antenna w/U.FL cable. 3. LSR 001-0015 2.4 GHz FlexNotch Antenna w/U.FL cable. 4. LSR 001-0001 center-fed 2.4 GHz dipole antenna and 080-0001 U.FL to Reverse Polarity SMA connector cable. When using the modules and or the reference designs that support the off module U.FL connector(s), you may use a substitute antenna if the antenna gain is less than or equal to +2 dBi. It may be possible to use a substitute chip antenna, however there are restrictions so please contact LSR for guidance prior to making any chip antenna substitutions. In addition to the Sterling-LWB Base SIP Module, LSR provides FCC Modular Certified reference design modules. The reference design modules are impedance-controlled PCBs that utilize microstrip trace design to route RF signals from the Sterling-LWB SIP module to the Antennas and coaxial connectors. Please use the latest CAD files from the LSR web site when incorporating the Sterling-LWB 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. Visit the LSR web site http://www.lsr.com for current PCB and Schematic CAD files.

LSR also offers two additional modular variants supplied on a carrier board. These modules function both as the reference design for the Sterling-LWB Module and as an all-inclusive module which can be assembled onto the end users host board. Depending on the users antenna and footprint needs, there is a module variant to suite most application requirements. LSR recommends that for simplicity of both the host PCB design, as well as the manufacturing process, that either the Chip Antenna or U.FL RF Connector version of the modules be used in your design. This section describes the details of the host PCB requirements. In order to use the modular certification for the LSR Sterling-LWB SIP Module and variants for your design, it is critical that the reference designs are correctly followed. To integrate LSR Sterling-LWB SIP Module into a design using a chip antenna, the full 4-layer Chip Antenna PCB reference design is shown in Figure 1, and Bill of Materials Table 4. Visit http://www.lsr.com. For the latest Schematics and CAD files. To integrate LSR Sterling-LWB SIP Module into a design using external U.FL connector, the full 4-

layer U.FL (external antenna) PCB reference design is shown in Figure 4 and Bill of Materials Table 6. http://www.lsr.com. For the latest Schematics and CAD files. 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 being used in your design as shown in Figure 1 and Figure 4. Each of the LSR Sterling-LWB modules use a high speed SDIO interface for communication between the host and the module. SDIO is quite sensitive to local sources of electrical noise that may exist as a result of improper PCB layout design thus the SDIO interface requires special attention when routing lines on the host PCB. SDIO paths should receive the highest priority when routing to proactively minimizing trace length to mitigate transmission line effects. All of the requirements for proper SDIO implementation is beyond the scope of this document, however some of the high level requirements and recommendations are:

50 ohm line impedance is required for all SDIO lines. Placing zero ohm resistor in-line on all SDIO lines to allow for line tuning (if required) on the host board. Keep all SDIO trace delay times as equal as possible For further information regarding the SDIO interface, see the most recent SDIO Physical Layer Specification provided by the SD Card Association.

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 re-

certifying 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. FCC also expects integrators to do spot checking of transmitter tests as necessary based upon KDB 996369 D04. 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 installed modules FCC ID and IC numbers need to be clearly marked on the product with the following verbiage Contains FCC ID: TFB-1003 and "Contains IC: 5969A-1003". 7.2 Module Integration Considerations - Antenna Systems The module must be used with one of the approved antennas:

1) LSR 001-0001 2.4 GHz center-fed dipole antenna and LSR 080-0001 U.FL to Reverse Polarity SMA connector cable. 2) LSR 001-0014 2.4 GHz FlexPIFA antenna. 3) LSR 001-0015 2.4 GHz FlexNotch antenna. 4) Johanson 2450AT18D0100 chip antenna. The antenna should be placed such that it is minimally disturbed by the products 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 modules certification is only valid for the list of approved antennas presented in section 6. When using the U.FL connector, you may use a substitute antenna if the peak antenna gain is to equal or less than +2.0 dBi.

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 not be 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 end-product is realized, the end-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, mid-frequency channel, and highest frequency channel. The supporting test data does not need to be submitted to the FCC or IC. The implementation of the module in a specific end-product should also be reviewed to ensure compliance with the FCC and IC requirements for SAR and MPE. In a portable application the minimum separation distance to the user is 29 mm. In a mobile application the minimum separation distance to the user is 20cm.
