The reconfigurable directional coupler includes a primary inductive segment, secondary inductive segments, and switch circuitry configured to change the total coupling capacitance formed between the primary and secondary inductive segments by selectively switching the secondary inductive segments into the secondary signal path. Simultaneously, the mutual inductance and coupling factor between the primary and the secondary inductive segments are reconfigured.
