  • Method and apparatus for transformer bandwidth enhancement
    Patent number: 6924724
    Abstract: A method and apparatus for transformer bandwidth enhancement is disclosed. In one embodiment, a transformer is provided for use in a high frequency communication environment. In one configuration, the transformer is configured with one or more compensation networks to improve high frequency operation and to reduce insertion loss at all frequencies. The compensation networks may be designed, in combination with a transformer, to create an equivalent all-pass symmetric lattice network having a frequency response in the desired range. In one embodiment, the compensation networks comprise a capacitance creating device which, when cross-connected to the transformer, increases transformer bandwidth.
    Type: Grant
