Radio frequency front-end transceiver of silent surface filter of multi-standard mobile terminal

Abstract

The invention discloses a radio frequency front-end transceiver of a silent surface filter of a multi-standard mobile terminal. The radio frequency front-end transceiver comprises a receiver, a frequency synthesizer and a transmitter, wherein the front end of the receiver is provided with one or more radio frequency tracking filters. According to the radio frequency front-end transceiver of the silent surface filter of the multi-standard mobile terminal, the radio frequency tracking filters are arranged in an integrated way, a plurality of sound surface filters are not necessarily arranged at input ends of the receiver of the transceiver of the radio frequency front-end transceiver, meanwhile, the number of number of the input ends in the receiver of the radio frequency front-end transceiver is reduced at the same time, therefore, the production cost of the mobile terminal is remarkably lowered, the area of an overall chip of the mobile terminal is reduced, the power consumption of the radio frequency tracking filters in the receiver in the radio frequency front-end transceiver is saved, the performance of the radio frequency tracking filters is improved, the overall performances and the market competitiveness of the mobile terminal are further improved, and great production practical significance is produced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a radio frequency front-end transceiver of a silent surface filter of a multi-standard mobile terminal. Background technique [0002] At present, with the development of smart phones and tablet computers, the business volume of global mobile data has increased significantly. Among them, the development of LTE (Long Term Evolution) technology not only improves the spectrum utilization rate of wireless communication, but also increases the data transmission rate and processable data capacity of wireless communication. [0003] At present, the wireless communication spectrum of LTE technology (frequency up to 3.8 GHz) can be divided into 43 bands, 1 to 21 bands are listed as LTE-FDD (Frequency Division Duplex), and 33 to 43 bands are listed as LTE-TDD ( time division duplex frequency band). [0004] As mobile operators expect that the amount of data usage for user co...

AI Technical Summary

Problems solved by technology

Therefore, the existing mobile terminals have more signal radio frequency input ports and more surface acoustic wave filters, resulting in higher production costs of the mobile terminal signal transceivers (ie, radio frequency front-end transceivers) and loss of mobile terminal The price competitive advantage of the mobile terminal greatly increases the overall chip area of ​​the mobile terminal. The chip area of ​​the mobile terminal is relatively large, which seriously affects the market application prospect of the mobile terminal.
