Method and apparatus for synthesizing dual band high-frequency signals for wireless communications

摘要

A method and apparatus for synthesizing high-frequency signals is disclosed that overcomes integration problem associated with prior implementations while meeting demanding phase noise and other impurity requirements. In one embodiment, on-package oscillator circuit inductors are provided for band selection purposes, with no external package connection to connect off-package or external inductors to on-package inductance circuits. Multiple package electrical connection points may also be provided on-package to allow for selection of alternate oscillator inductance values during package assembly.
