Si4460/61/63/64/67/68 RF ICs Layout Design Guide

PublishTime： 2018-05-25 Manufacturer： Silicon Labs Type： Application note & Design Guide Language： English

The purpose of this application note is to help users design PCBs for the next generation EZRadioPRO™ RF ICs, i.e. the Si4460/61/63/64/67/68 devices (henceforth referred to as EZRadioPRO™ RF ICs) using good design practices that allow for good RF performance. The matching principles described in detail in "AN627: Si4460/61/67Low-Power PA Matching" and in "AN648: Si4063/Si4463/64/68 TX Matching".
The RF performance and the critical maximum peak voltage on the output pin strongly depend on the PCB layout as well as the design of the matching networks. For optimal performance, Silicon Labs recommends the use of the PCB layout design hints described in the following sections.
