Abstract:
1. An apparatus, comprising: a printed circuit board (PCB) formed from low loss materials associated with high speed data transfer, the PCB defining a first outer surface and a second outer surface opposite the first outer surface, the PCB having a recess in the first outer surface of the PCB, the PCB having a signal layer between the first outer surface and the second outer surface, the signal layer including a first circuit line having a first portion exposed within the recess and a second portion exposed within the recess, the first circuit line being devoid of electrical contact with vias, the signal layer including a second circuit line having a first portion exposed within the recess and a second portion exposed within the recess, the second circuit line being devoid of electrical contact with vias; a first component disposed within the recess and connected to the first portion of the first circuit line and the second portion of the first circuit line such that an entirety of the first component is within the recess and below the first outer surface; and a second component disposed within the recess and connected to the first portion of the second circuit line and the second portion of the second circuit line such that an entirety of the second component is within the recess and below the first outer surface, the first component and the second component collectively defining a differential pair, a characteristic impedance mismatch associated with at least one of the first circuit line or the second circuit line being mitigated based on the first circuit line and the second circuit line being devoid of electrical contact with the vias.
