Abstract

This circuit allows for automatic RF path selection based on the presence of the external antenna instead of the external adapter. By sensing the external antenna instead of the adapter, the circuit assures that RF remains routed to the internal antenna if the external antenna is inadvertently not connected to the external adapter.
