Patent number: 11722101Abstract: Apparatus and methods for a modified Doherty amplifier operating at gigahertz frequencies are described. The combining of signals from a main amplifier and a peaking amplifier occur prior to impedance matching of the amplifier's output to a load. An output impedance-matching element can be relied upon. In one example, the output impedance-matching element can include an output strip line, a shunt capacitor connected between the output strip line and ground, an output capacitor connected between the output strip line and an output bonding pad, and an inductive strip line connected between the output bonding pad and ground.Type: GrantFiled: December 17, 2021Date of Patent: August 8, 2023Assignee: MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.Inventors: Gerard Bouisse, Andrew Alexander, Andrew Patterson

Patent number: 11716058Abstract: Apparatus and methods for a multiclass, broadband, no-load-modulation power amplifier are described. The power amplifier (500) may include a main amplifier (532) operating in a first amplification class and a plurality of peaking amplifiers (536, 537, 538) operating in a second amplification class. The main amplifier (532) and peaking amplifiers (536, 537, 538) may operate in parallel on portions of signals derived from an input signal to be amplified. The main amplifier (532) may see no modulation of its load impedance between a fully-on state of the power amplifier (all amplifiers amplifying) and a fully backed-off state (peaking amplifiers idle). By avoiding load modulation, the power amplifier (500) can exhibit improved bandwidth and efficiency compared to conventional Doherty amplifiers.Type: GrantFiled: February 10, 2022Date of Patent: August 1, 2023Assignee: MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.Inventor: Gerard Bouisse

Patent number: 11705869Abstract: Apparatus and methods for a low-load-modulation power amplifier are described. Low-load-modulation power amplifiers can include multiple amplifiers connected in parallel to amplify a signal that has been divided into parallel circuit branches. One of the amplifiers can operate as a main amplifier in a first amplification class and the remaining amplifiers can operate as peaking amplifiers in a second amplification class. The main amplifier can see low modulation of its load between the power amplifier's fully-on and fully backed-off states. Improvements in bandwidth and drain efficiency over conventional Doherty amplifiers are obtained.Type: GrantFiled: October 4, 2019Date of Patent: July 18, 2023Assignee: MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.Inventors: Bi Ngoc Pham, Gerard Bouisse
