Abstract
A directional coupler utilizes an inductive element of a power amplifier and a coupled conductive element. The inductive element of the power amplifier is a functioning element within the power amplifier and at least part of the inductive element of the power amplifier is disposed in a multi-layer substrate. At least part of the coupled conductive element is disposed in the multi-layer substrate. The coupled conductive element is configured to be inductively coupled to the inductive element of the power amplifier such that the coupled conductive element carries a first RF signal that is representative of a second RF signal within the inductive element of the power amplifier.
