Abstract
The utility model provides a radio-frequency front end with independent transmission and reception channels. The radio-frequency front end comprises a radio-frequency transmission-reception controller, and a transmission channel and a reception channel which are connected with the radio-frequency transmission-reception controller. The radio-frequency front end is characterized in that the radio-frequency front end is provided with independent transmission and reception antennas; and an output end of the transmission channel is connected with the transmission antenna, and an input end of the reception channel is connected with the reception antenna. According to the radio-frequency front end provided by the utility model, the radio-frequency transmission and reception channels are independent, so that the loss of the signals and interference between the signals can be effectively reduced, thereby improving the performance of the antennas.
Description
Technical field
The utility model relates to independently radio-frequency front-end of a kind of transceiver channel
Background technology
Existing mobile phone front end can comprise many emission paths and receive path, generally realize each path sharing antenna by duplexer, as shown in Figure 1.Though such design makes the mobile phone radio frequency circuit more compact, maximally utilise the mobile phone volume inside, but many limitations are arranged also: one, because antenna is wanted the signal transmission of compatible a plurality of frequency ranges, mobile phone environment is harsh all the more in addition, makes the design difficulty of antenna for mobile phone continue to increase; Two, the interference between the loss of duplexer and each frequency band signals influences communication quality to some extent; Three, because antenna to the requirement in space, makes the appearance design of mobile phone also be restricted.
Summary of the invention
The utility model proposes independently radio-frequency front-end of a kind of transceiver channel, can effectively reduce loss and the interference between signals of signal, effectively promote antenna performance.Its technical scheme is as follows:
A kind of transceiver channel is radio-frequency front-end independently, comprises radio-frequency receiving-transmitting controller, the emission path that is connected with the radio-frequency receiving-transmitting controller and receives path, and it is characterized in that: described radio-frequency front-end is provided with independently transmitting antenna and reception antenna; The output of described emission path is connected with transmitting antenna, and the input of described reception path is connected with reception antenna.
Such scheme is independent with transmission channel and receive path, has avoided the sending and receiving interference between signals, promotes antenna performance effectively.
Further, described radio-frequency front-end comprises one or more emission path, and each output of launching path is connected with a transmitting antenna respectively.Such scheme is further independent with each emission path, can reduce the interference between signal effectively, has avoided simultaneously switching the loss that produces owing to use duplexer to carry out channel.
Further, described radio-frequency front-end comprises that one or more receives path, and each input that receives path is connected with a reception antenna respectively.It is independent that each receives path, can reduce interference between signal and the loss of switching device to greatest extent.
Another kind as such scheme improves, and described radio-frequency front-end is provided with a multichannel duplexer, and each path of described duplexer is connected with the output of each emission path respectively, and duplexer is connected with a transmitting antenna.
Further, described radio-frequency front-end comprises that one or more receives path, and each input that receives path is connected with a reception antenna respectively.It is independent that each receives path, can reduce interference between signal and the loss of switching device to greatest extent.
Advantage of the present utility model is: 1, simplified structure of radio-frequency front end, exempted the loss of partial circuit device to signal; 2, each radiofrequency signal sending and receiving port is arranged independently antenna, strengthen antijamming capability; 3, antenna only at single emission path or reception path, further requires to reduce to antenna, makes that the design of each antenna is more flexible.

As shown in Figure 3, execution mode two:
A kind of transceiver channel is radio-frequency front-end independently, comprises radio-frequency receiving-transmitting controller, the 2G that is connected with the radio-frequency receiving-transmitting controller and 3G path, and a multichannel duplexer; Described 2G path comprises: GSM high-frequency emission path, GSM low frequencies path, GSM high frequency receive path and the GSM low frequency receives path; Described 3G path comprises: WCDMA emission path and WCDMA receive path.The output of GSM high-frequency emission path, GSM low frequencies path and WCDMA emission path is connected with each path of duplexer respectively, and described duplexer is connected with antenna one.The GSM high frequency receives path and is connected with antenna five, and the GSM low frequency receives path and is connected with antenna six, and WCDMA receives path and is connected with antenna four.
Such scheme requires to reduce to antenna, makes that the design of antenna and layout are more flexible, and many antenna arrangement are realized in the inner space that can take full advantage of mobile hand-held devices such as mobile phone.
Above-mentioned is preferred embodiments of the present utility model, but does not limit enforcement of the present utility model with this.All and the technical solution of the utility model identical, approximate or equivalents, the improvement done based on this all belong to the protection range of this patent.
