TUNABLE DIFFERENTIAL VIA CIRCUIT

A circuit of tunable differential vias may include a first tunable via circuit configured to couple a first signal of a differential signal pair from a first outer surface of a printed circuit board (PCB) to a second outer surface of the PCB. The circuit may further include a second tunable via circ...

More Information
Summary:A circuit of tunable differential vias may include a first tunable via circuit configured to couple a first signal of a differential signal pair from a first outer surface of a printed circuit board (PCB) to a second outer surface of the PCB. The circuit may further include a second tunable via circuit configured to couple a second signal of the differential signal pair from the first outer surface of the PCB to the second outer surface of the PCB. The first tunable via circuit may further include a first buried via spatially offset from the second tunable via circuit to cause a predetermined impedance for the first and second signals through the first and second tunable via circuits at an operating frequency.
