Problems solved by technology

[0004] However, the power amplifier device with the above-mentioned three-dimensional architecture can only process the input signal of a single frequency band. Under the condition that the electronic device needs to have the processing capability of the input signal of multiple frequency bands, providing a new type of power amplifier device will become an important task for the designer. subject

Embodiment Construction

[0039] Please refer to figure 1 , figure 1 A schematic diagram of a power amplifying apparatus 100 according to an embodiment of the present invention is shown. The power amplifier device 100 includes a substrate 120 and power amplifiers 111 to 114 . The power amplifiers 111 to 114 are disposed on the substrate 120, and the power amplifiers 111 to 114 receive the input signals IN1 to IN4, respectively. The power amplifiers 111-114 amplify the received input signals IN1-IN4, and thereby generate output signals OUT1-OUT3. Wherein, in this embodiment, for the reason of long term evolution (Long Term Evolution, LTE) data linearity, the input signals IN3 and IN4 are signals in the same frequency band, and the input signals IN1 and IN3 are signals in different frequency bands. On the other hand, the input signal IN2 and the input signal IN3 are also signals of different frequency bands.

[0040] Moreover, in this embodiment, the input signals IN3 and IN4 are input signals of the...

Abstract

A power amplification device includes a first substrate and N power amplifiers. N power amplifiers are arranged on the first substrate. The power amplifiers respectively receive N input signals. Wherein, at least two of the input signals have different frequency bands. In addition, the power amplifier generates M output signals respectively, where N is a positive integer greater than 1, and M is a positive integer not greater than N.

Description

technical field [0001] The present invention relates to a power amplifying device, and more particularly, to a power amplifying device capable of processing signals of various frequency bands. Background technique [0002] With the rapid development of wireless communication technology, it has become a necessary requirement for electronic devices to have a wireless communication function. However, under the premise of using a lower-cost CMOS process, the problems of lower breakdown voltage and higher substrate loss must be overcome. Therefore, in the design of the power amplifier, in the known technical field, there are proposed technical means to use a transformer to perform power synthesis, so as to reduce the size of the transistor and increase the output power. [0003] In the known technology, a power amplifier device with a three-dimensional structure is proposed, and a power amplifier with a symmetrical structure is used to receive the incoming signal, and amplify th...
