Title:
POWER AMPLIFIER MODULE
Document Type and Number:
Japanese Patent JP2022170177
Kind Code:
A
Abstract:
To miniaturize a power amplifier module for communication that combines different frequency bands.SOLUTION: A power amplifier module includes an output switch including a plurality of input terminals, and a plurality of output terminals, and capable of electrically connecting each of the plurality of input terminals to at least one of the plurality of output terminals, a first low noise amplifier that amplifies a signal in a predetermined frequency band input through an antenna that receives signals in a plurality of frequency bands and outputs a first signal to a first input terminal among the plurality of input terminals, and a second low noise amplifier that amplifies a signal in a predetermined frequency band input through an antenna that receives signals in a plurality of frequency bands, and outputs a second signal to a second input terminal different from the first input terminal among the plurality of input terminals, where a filter that attenuates signals in a frequency band higher than the frequency band of the second signal is electrically connected between the second input terminal and the second low noise amplifier.SELECTED DRAWING: Figure 1
