Patent number: 7102444Abstract: A method and apparatus for an amplifier, such as a radio frequency amplifier embodiment as an integrated circuit is disclosed. Embodiments provide for operating with good energy efficiency at multiple power levels. Resonant components act to provide consistent operating parameters over the wide range of power levels used. A compensating impedance is switched into or out of circuit in high power mode to improve the match that would pertain without the compensation. Improved compensation and linearity may be provided using features disclosed. The invention may operate in the microwave region or at other RFs.Type: GrantFiled: September 24, 2004Date of Patent: September 5, 2006Assignee: ANADIGICS, Inc.Inventors: Payman Hosseinzadeh Shanjani, Hamid Reza Rategh
