A method and apparatus for synthesizing high-frequency signals that overcomes integration problems 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.

[ We claim:] [1.]1. A semiconductor package comprising:a package substrate having a first surface;an integrated circuit electrically connected to said first surface of said package substrate, said integrated circuit and said package substrate together forming said semiconductor package, the integrated circuit and package substrate including frequency synthesizer circuitry; andat least one inductance circuit formed entirely within said semiconductor package and formed at least partially between said integrated circuit and said package substrate, the inductance circuit at least in part determining an output frequency for the frequency synthesizer circuitry;wherein said frequency synthesizer circuitry has an output frequency selectably operable within a plurality of bands, and wherein said at least one inductance circuit forms part of a controlled oscillator circuit within said frequency synthesizer circuitry, the output frequency being dependent upon the controlled oscillator circuit.
