[0002] As we all know, there are many 5G frequency bands in China, and there are problems with the RF front-end amplifier module. It only supports amplifying RF signals of a certain frequency band, and different frequency bands require different RF receiving modules and transmitting modules. For example, in a 5G five-mode device that supports RF signals of five frequency bands (N28, N1, N41, N78, N79), a total of five RF modules are required.

[0003] Since the existing 5GNR RF power amplifier cannot support the reception and amplification of RF signals in five frequency bands, when the equipment needs to support RF signals in multiple frequency bands, it must have multiple RF power amplifiers and low-noise amplifier modules, which will inevitably cost a lot of money.
