Title:
AMPLIFIER MODULE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/241491
Kind Code:
A1
Abstract:
This amplifier module comprises a Doherty amplifier circuit. The Doherty amplifier circuit includes a first transistor chip that constitutes a carrier amplifier, a first output signal line that transmits a first amplified signal outputted from the carrier amplifier, a second transistor chip that constitutes a peak amplifier, and a second output signal line that transmits a composite signal of the first amplified signal and a second amplified signal outputted from the peak amplifier. The direction from a drain terminal of the second transistor chip toward a connection part with a first bonding wire in a first conductor of the first output signal line and the direction from the drain terminal of the second transistor chip toward a connection part with a second bonding wire in the second conductor of the second output signal line are the same direction.
