摘要： A power amplifier arrangement for amplifying signals with multiple frequency bands. The power amplifier arrangement includes multiple inputs, multiple outputs, multiple main amplifiers, and multiple auxiliary amplifiers. Each of the multiple main amplifiers is configured as a narrow band amplifier for amplifying a signal within one frequency band of the multiple frequency bands, each auxiliary amplifier is configured as a wideband amplifier for amplifying signals within at least two frequency bands of the multiple frequency bands. The power amplifier arrangement further includes one or more input hybrid couplers and one or more output hybrid couplers.
