| 摘要 |
A high frequency, large bandwidth electronic device (300) for transforming balanced/unbalanced electrical signals. In one embodiment, the device (300) comprises an auto-transformer (318) mounted on substrate (312c) interposed between the balanced (102) and unbalanced port (104) so as minimize parasitic losses. Bonded bi-filar wire (318b) is wound around the auto-transformer core (318a) which facilitates a low, balanced leakage inductance thereby further enhancing device bandwidth. A method of manufacturing the aforementioned electronic device is also disclosed.
