Abstract
Integrated filter and electromagnetic coupler assemblies. In certain examples, an integrated filter and electromagnetic coupler assembly includes a filter having a capacitance and a series inductance, the series inductance being connected between an input port and an output port of the integrated filter and electromagnetic coupler assembly, and combination of the capacitance and the series inductance being selected to provide the filter with a passband and a stopband. The integrated filter and electromagnetic coupler assembly further includes a coupling element positioned physically proximate the series inductance and extending between a coupled port and an isolation port of the integrated filter and electromagnetic coupler assembly, the integrated filter and electromagnetic coupler assembly being configured to provide at the coupled port a coupled signal via inductive coupling between the series inductance and the coupling element responsive to receiving an input signal at the input port.
