Embodiment approach

[0031] Antenna 1 has two implementations: first, antenna 1 includes multiple sub-antennas, each of which is used to transmit and receive radio frequency signals of one frequency band; second, antenna 1 is a multi-band antenna for transmitting and receiving multiple frequency bands. radio frequency signal

[0032] In the first embodiment of the multi-standard multi-mode wireless transceiver shown in FIG. 2, the radio frequency receiver 2 includes a multi-band LNA (low noise amplifier) ​​connected to the antenna 1 and used to respond to and increase the strength of radio frequency signals in multiple frequency bands ) 21, the signal can first pass a band-pass filter to filter out interfering signals located in other frequency bands, and then amplify through the LNA to increase the strength of weak signals in the useful frequency band. The multi-band LNA 21 is composed of multiple LNAs, and each LNA corresponds to a wireless frequency band, and the baseband processing circuit 4...

Abstract

The invention provides a multi-standard multi-mode wireless transceiver, comprising an antenna, a radio-frequency receiver, a radio-frequency emitter, a frequency synchronizer, and a baseband processing circuit; the frequency synchronizer is used for generating at least two local oscillation signals required by modulation and demodulation and outputting the local oscillation signals to the radio-frequency receiver and the radio-frequency emitter; the antenna is a multi-frequency antenna which can respond toe a plurality of frequency signals; the radio-frequency receiver comprises a multi-frequency LNA which is connected with the antenna and used for responding to and increasing the radio-frequency signal intensity of a plurality of frequencies; the radio-frequency emitter comprises a multi-frequency PA which is connected with the antenna and used for responding to and amplifying the radio-frequency signal powers of a plurality of frequencies. The multi-standard multi-mode wireless transceiver is the wireless transceiver which can be applied to the worldwide range with a plurality of modes.

Description

technical field [0001] The present invention relates to a wireless transceiver, in particular to a multi-standard multi-mode wireless transceiver; the present invention also relates to a receiver, in particular to a multi-standard multi-mode wireless receiver; the present invention also relates to a transmitter , especially a multi-standard multi-mode wireless transmitter; the invention also relates to a frequency synthesizer, especially a multi-standard multi-mode wireless frequency synthesizer. Background technique [0002] The advent of technologies such as wireless local area networks, digital video broadcasting, and third-generation W-CDMA has made wireless communications an increasingly important area of ​​research and development. The rapid development of wireless mobile networks has led to the need for high-performance, low-power, and low-cost RF IC designs. Wireless standards are constantly evolving. Different wireless standards, such as WLAN, WiMAX, GPS, DVB and c...
