Title:
ロバストなＡＭ－ＰＭひずみ自己抑制技術を備えた超小型のマルチバンド送信器
Document Type and Number:
Japanese Patent JP7030891
Kind Code:
B2
Abstract:
A communication device includes a power amplifier that generates power signals according to one or more operating bands of communication data, with the amplitude being driven and generated in output stages of the power amplifier. The final stage can include an output passive network that suppresses suppress an amplitude modulation-to-phase modulation (AM-PM) distortion. During a back-off power mode a bias of a capacitive unit of the output power network component can be adjusted to minimize an overall capacitance variation. An output passive network can further generate a flat-phase response between dual resonances of operation.
