Abstract:
1. A microstrip coupler comprising: an input microstrip conductor configured to carry an input signal; a central microstrip conductor proximate the input microstrip conductor and separated from the input microstrip conductor by a first gap; an output microstrip conductor proximate the central microstrip conductor and separated from the central microstrip conductor by a second gap; and a coupling microstrip conductor for coupling at least a portion of the input signal; wherein the coupling microstrip conductor comprises: a first coupled portion disposed along a first side of the central microstrip conductor; a second coupled portion disposed along a second side of the central microstrip conductor; a first connecting portion extending through the first gap and beneath the first controlled capacitance bridge for connecting a first end of the first coupled portion and a first end of the second coupled portion; and a second connecting portion extending through the second gap and beneath the second controlled capacitance bridge for connecting a second end of the second coupled portion.
