Multi-layered spiral couplers on a fluropolymer composite substrate |
摘要 |
A microwave circuit utilizes a spiral-like coupler configuration to achieve the functionality of a traditional coupler with higher density and lower volume. A plurality of substrate layers having metal layers disposed on them are bonded to form the package. A plurality of groundplanes may be used to isolate the spiral-like shape from lines extending out to contact pads or other circuitry.
