Abstract

A transceiver, the transmitter includes: a baseband control device (21); a frequency up-conversion device (22), connected to the baseband control device (21), for up-converting a baseband signal generated by the baseband control device (21) to obtain Intermediate frequency signal; at least two radio frequency channels (23) arranged in parallel are connected to the up-conversion device (22) through a second switch (S2) to convert, amplify and filter the intermediate frequency signal to obtain the radio frequency of its corresponding part of the frequency band The signal; the antenna (24), connected in series with the output end of any one of the at least two radio frequency channels (23) through the first switch (S1), and used to send out the radio frequency signal obtained by the radio frequency channel. By setting at least two radio frequency channels in parallel, each radio frequency channel covers a certain frequency range and works at different operating frequency points, so as to achieve ultra-wide bandwidth while maintaining high wireless communication performance.

Description

technical field [0001] The embodiments of the present application relate to wireless communication technologies, and in particular, to a transceiver. Background technique [0002] With the continuous development of society, people's demand for wireless communication service capacity is also continuously increasing. As wireless communication develops from 2G to 3G and then to 4G, the improvement of service capacity is always the most important content. Therefore, wireless transceivers supporting large service capacity are required to have the characteristics of broadband. However, traditional wireless communication usually works in the wireless spectrum lower than 6GHz, and it is difficult to meet the demand for continuous growth of business capacity. In addition, all countries in the world have strict and clear divisions of wireless difference. Therefore, the development of ultra-wideband wireless communication adapted to the spectrum allocation of various countries has at...
