发明名称 Amplifier module with two power amplifiers for dual band cellular phones
摘要 Disclosed is an amplifier module suitable for automated mounting and connecting to a motherboard of a cellular phone. The amplifier module comprises a substrate which has at least two layers of electrically conducting material. On the substrate, a first and second semiconductor chip are mounted. The first semiconductor chip includes a first integrated circuit which forms part of a first power amplifier adapted for a first radio frequency band. The second semiconductor chip includes a second integrated circuit which forms part of a second power amplifier adapted for a second radio frequency band. The first and second chips are positioned on the substrate and electrically connected to components mounted on the substrate.
