Abstract:
1. An electronic device, comprising: (a) a first stripline circuit layer having a first stripline circuit disposed between a first ground layer and a second ground layer, said first stripline circuit layer further having a first dielectric layer disposed between said first ground layer and said first stripline circuit to isolate said first stripline circuit from said first ground layer, said first stripline circuit layer further having a second dielectric layer disposed between said first stripline circuit layer and said second ground layer to isolate said first stripline circuit layer from said second ground layer; (b) a second stripline circuit layer stacked directly on said first stripline layer, said second stripline circuit layer having a second stripline circuit disposed between said second ground layer and a third ground layer, said second stripline circuit layer further having a third dielectric layer disposed between said second stripline circuit and said second ground layer to isolate said second stripline circuit from said second ground layer, said second stripline circuit layer further having a fourth dielectric layer disposed between said second stripline circuit and said third ground layer to isolate said second stripline circuit from said third ground layer, said second ground layer being disposed between said first stripline circuit and said second stripline circuit to provide shielding between said first stripline circuit layer and said second stripline circuit layer; (c) a first signal trace disposed on said first dielectric layer adjacent said first ground layer, (d) a first via passing interiorly through said first dielectric layer and electrically coupling said first signal trace to said first stripline circuit; (e) a second signal trace disposed on said first dielectric layer adjacent said first ground layer, (f) a second via passing interiorly through said first dielectric layer, said second dielectric layer, said third dielectric layer, and said second ground layer, said second via electrically coupling said second signal trace to said second stripline circuit.
