Problems solved by technology

Generally speaking, current RF transceivers are designed for one frequency band and one mode (single-mode single-frequency) applications. Multi-band applications usually require multiple RF transceivers to work together, which not only increases power consumption, but also increases chip cost

Abstract

The invention discloses a multimode multifrequency transceiver, which comprises a radio frequency front-end module, an analog baseband module and a frequency synthesizer module. The frequency front-end module comprises a plurality of radio frequency links used for receiving and dispatching signals in different frequency ranges; the analog baseband module comprises an analog baseband signal receiving link and an analog baseband signal emission link, and is used for carrying out filter and amplification on signals sent by the radio frequency links, converting the signals into digital signals, carrying out digital to analog conversion and filtering amplification processing on signals transmitted by a digital baseband, and outputting the signals to the radio frequency links, and the multimode multifrequency transceiver shares the analog baseband signal receiving link and the analog baseband signal emission link; and the frequency synthesizer module is utilized to provide different eigenfrequencies for the plurality of radio frequency links. The working frequency bandwidth of the ultrawideband multimode multifrequency transceiver provided by the invention can cover 0.3GHz to 6GHz, so that the ultrawideband multimode multifrequency transceiver is suitable for a plurality of different wireless communication standards.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a multi-mode, multi-frequency communication system. Background technique [0002] With the rapid development of wireless communication technology and the emergence of new technologies and standards, users hope to freely access the corresponding network to communicate according to their own needs through multi-mode terminals in their hands, so as to realize flexible, convenient and unlimited free communication. , the future development trend will be the continuous integration of various wireless technologies. At the same time, a large number of frequency bands related to communication, mobile, and satellite positioning exist in the commonly used civil standard frequency bands (such as <6GHz frequency bands). [0003] For example, UHF band (470-798MHz) and S band (2635-2660MHz) are Chinese digital TV bands. With the rapid development of wireless communication technology, dig...
