| 摘要 |
A high frequency, large bandwidth electronic device for transforming balanced/unbalanced electrical signals. In one embodiment, the device comprises an auto-transformer mounted on substrate interposed between the balanced and unbalanced port so as minimize parasitic losses. Bonded bi-filar wire is wound around the auto-transformer core which facilitates a low, balanced leakage inductance thereby further enhancing device bandwidth. A method of manufacturing the aforementioned electronic device is also disclosed.
