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 module’s 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:

LSR 001-0001 2.4 GHz center-fed dipole antenna and LSR 080-0001 U.FL to Reverse Polarity SMA connector

cable.

LSR 001-0014 2.4 GHz FlexPIFA antenna.

LSR 001-0015 2.4 GHz FlexNotch antenna.

Johanson 2450AT18D0100 chip 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.

6.3 Module Integration Considerations - Substitute Antenna Systems

The module’s 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.
