The invention provides a multi-input multi-output transceiver. A first transmitting channel comprises a first power amplifier and a first transmission line which are serially connected. A second transmitting channel comprises a second power amplifier. The common end of a first single-pole double-throw switch is connected with the second power amplifier. A first throw end is connected onto the first power amplifier through a second transmission line. The common end of a second single-pole double-throw switch is connected with the second power amplifier. The first throw end is connected onto the first power amplifier through a third transmission line. A second throw end is connected onto a second antenna. When the common end of the first single-pole double-throw switch is connected onto the first throw end and the common end of the second single-pole double-throw switch is connected onto the first throw end, the power amplifier balancing function can be realized by the first power amplifier, the second power amplifier, the second transmission line and the third transmission line collectively.
Description
technical field [0001] The invention relates to a transceiver, in particular to a multiple-input multiple-output transceiver. Background technique [0002] With the increasing popularity of wireless network applications, the requirements for the transmission distance of radio frequency signals sent by wireless devices are getting higher and higher. Only when radio frequency signals are transmitted farther can the wireless transmission function be realized. At present, most existing technologies increase the transmission distance of radio frequency signals by changing the shape of the antenna of the wireless device and increasing the gain of the antenna of the wireless device, but the antenna of the wireless device itself has a certain distance limit. Therefore, there is an urgent need to provide a method that can effectively increase the transmission distance of the radio frequency signal sent by the wireless device. Contents of the invention [0003] In view of this, it ...
