Sterling-LWB Module APPLICATION GUIDE 4 Sterling-LWB Module PCB Layout Requirements Since the modules and their 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 these modules into an end-product, and is solely responsible for the Unintentional Emissions levels produced by the end-product.
Sterling-LWB Module APPLICATION GUIDE 5 Sterling-LWB Reference Design Modules The LSR Sterling-LWB Module is supplied as a SIP package. 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 user’s antenna and footprint needs, there is a module variant to suite most application requirements.

Sterling-LWB Module APPLICATION GUIDE 7 EMC Compliance 7.1 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 recertifying the radio module.
Sterling-LWB Module 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.
