Title:
HIGH FREQUENCY POWER AMPLIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/176947
Kind Code:
A1
Abstract:
A high frequency power amplification device (200) comprises, on a first main surface (101) of a multilayer sub-mount substrate (100): a carrier amplification semiconductor device (11); a peak amplification semiconductor device (12); a bias power supply semiconductor device (13); a second high frequency signal line (2) for transmitting a high frequency signal to the carrier amplification semiconductor device (11) or the peak amplification semiconductor device (12); and a bias power supply line (31) for carrier amplification which is wired by means of a third wiring layer (105) to supply a bias power supply voltage. The second high frequency signal line (2) and the bias power supply line (31) for carrier amplification intersect each other in plan view. A second wiring layer (104) between a first wiring layer (103) and the third wiring layer (105) is provided with a shield pattern (121) at ground potential, and one or more connection-vias (131) disposed along an extending direction of the bias power supply line (31) for carrier amplification, wherein the one or more connection-vias (131) are connected to the shield pattern (121).
