Power amplifier for pRRU and pRRU power amplification all-in-one machine

The invention provides a power amplifier used for a pRRU and a pRRU power amplification all-in-one machine. The power amplifier used for the pRRU comprises a first MIMO channel and a second MIMO channel. The first MIMO channel comprises two first combiners, and a first uplink and a first downlink which are connected in parallel between the two first combiners; the second MIMO channel comprises two second combiners as well as a second uplink, a second downlink, a third uplink and a third downlink which are connected in parallel between the two second combiners; each first MIMO channel and each second MIMO channel further comprise two time slot control switches to control switching of uplink and downlink signals. The power amplifier supports the MIMO technology, can amplify and upgrade the power of the traditional pRRU, enhances the product coverage capability, and can be widely applied to indoor and outdoor coverage of large and medium scenes. 本发明提供了一种用于pRRU的功率放大器及pRRU功率放大一体机，该用于pRRU的功率放大器包括第一MIMO通道和第二MIMO通道；第
