Sterling-LWB5 Module APPLICATION GUIDE 6 EMC Compliance 6.1 Summary The Sterling-LWB5 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-LWB5 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.
