2.2.3.2 Routing Example
Interface to RF Connector
Figure 26 shows the connection of the module‘s antenna pad with an application PCB‘s coaxial
antenna connector. Please note that the ELS81-US bottom plane appears mirrored, since it is
viewed from ELS81-US top side. By definition the top of customer's board shall mate with the
bottom of the ELS81-US module.
