Assignee: VIASAT INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. A method of manufacturing a power amplifier, the method comprising:
providing a plurality of packaged semiconductor chips each including respective first and second amplifier stages, the respective second amplifier stage having an input coupled with an output of the respective first amplifier stage, the packaged semiconductor chips each also including an internal bias coupling path electrically routing a first direct-current (DC) contact pad to a second DC contact pad and an input of the respective first amplifier stage;
providing a first circuit board;
forming first electrical connections in the first circuit board for connecting to a first subset of the plurality of packaged semiconductor chips; and
surface mounting the first subset of the plurality of packaged semiconductor chips on the first circuit board in a first multi-stage power amplifier configuration;
wherein the first electrical connections comprise parallel daisy-chain connections between respective internal bias coupling paths of at least two of the first subset of the plurality of packaged semiconductor chips.
