Abstract
The invention relates to the technical field of communication and provides a transceiver. In the prior art, the transceiver only guarantees that only one frequency band can be used at the same time, thereby having a narrow application range. The transceiver solves the problem in the prior art. The transceiver is applied to a mobile terminal and comprises a duplexer, an adjusting unit and a control unit. The adjusting unit comprises an adjustable matching circuit and an adjustable band rejection filter. The adjusting unit is connected with the control unit and an antenna. The duplexer comprises a first input end, a second input end and an output end. A first frequency band filter is connected between the first input end and the output end. A second frequency band filter is connected between the second input end and the output end. The output end is connected with the antenna. The control unit is used for adjusting and controlling the adjustable matching circuit and the adjustable band rejection filter, so as to adjust the working frequency band of the antenna to a plurality of preset frequency bands of a target coverage frequency band range of the antenna, so that the technological effect of simultaneous receiving and transmitting at two frequency bands at the same time is realized.

But existing mode regulates, only can ensure to only have a frequency range to use at synchronization, the scope therefore used is narrower.
Summary of the invention
The present invention is by providing a kind of transceiver, solve transceiver of the prior art and only can ensure to only have a frequency range to use at synchronization, therefore the scope used is narrower, and then achieves the technique effect simultaneously can received and dispatched in two frequency ranges at synchronization.
The technical scheme of the embodiment of the present invention is specially:
A kind of transceiver, be applied to mobile terminal, comprise duplexer, regulon and control unit, regulon comprises adjustable match circuit and tunable band-stop filter, regulon is connection control unit and antenna respectively, and duplexer comprises first input end, the second input, output, is connected the first frequency band filter between first input end with output, the second input be connected the second frequency band filter between output, output connect antenna;
Control unit is used for carrying out regulable control to adjustable match circuit and tunable band-stop filter, the working frequency range of antenna to be adjusted to default two frequency ranges in the target coverage frequency band range of antenna.
Further, described first frequency band filter comprises multiple first resonator, and described second frequency band filter comprises second resonator, connects the series resonant circuit of first input end and the second input and the second resonator.
Further, also comprise the filtration module be connected with described output, described filtration module is used for the signal of non-first frequency range of filtering and non-second frequency range.
The one or more technical schemes provided in the embodiment of the present invention, at least have following technique effect or advantage:
Owing to adopting duplexer, regulon, control unit, antenna in a transceiver, regulon comprises adjustable match circuit and tunable band-stop filter, regulon is connection control unit and antenna respectively, duplexer comprises first input end, the second input, output, the first frequency band filter is connected between first input end with output, the second input be connected the second frequency band filter between output, output connect antenna; Control unit is used for carrying out regulable control to adjustable match circuit and tunable band-stop filter, the working frequency range of antenna to be adjusted to the default multiple frequency range in the target coverage frequency band range of antenna, to solve transceiver in prior art and only can ensure the technique effect simultaneously received and dispatched in two frequency ranges at synchronization.
Accompanying drawing explanation
Fig. 1 is the structural representation of transceiver in the embodiment of the present invention.
Embodiment
The present invention is by providing a kind of transceiver, solve transceiver of the prior art and only can ensure to only have a frequency range to use at synchronization, therefore the scope used is narrower, and then achieves the technique effect simultaneously can received and dispatched in two frequency ranges at synchronization.
There is transceiver only a frequency range can be only had to use at synchronization to solve in above-mentioned prior art, therefore, the technical problem that the scope used is narrower, is described in detail technique scheme below in conjunction with Figure of description and concrete execution mode.
A kind of transceiver that the embodiment of the present invention provides, as shown in Figure 1, comprise duplexer 101, regulon 102, control unit 103, antenna 104, this regulon 102 includes adjustable match circuit 1021 and tunable band-stop filter 1022, regulon 102 connection control unit 103, duplexer 101 comprises first input end 1011, second input 1012, output 1013, the first frequency band filter 1014 is connected between first input end 1011 with output 1013, the second input 1012 be connected the second frequency band filter 1015 between output 1013, this output 1013 connects antenna 104, .
In a particular embodiment, the signal exported by duplexer 101 output, regulate via regulon 102, particularly, this control unit 103 is for carrying out regulable control to this adjustable match circuit 1021 and tunable band-stop filter 1022, the working frequency range of this antenna 104 to be adjusted to the default multiple frequency range in the target coverage frequency band range of antenna 104, like this, Signal Regulation to be sent to different frequency range can be sent.
Particularly, realized by following device in the process received while this duplexer 101 and send, this first frequency band filter 1014 comprises multiple first resonator, this second frequency band filter comprises second resonator, connects the series resonant circuit of this first input end and the second input and the second resonator, to ensure, this duplexer 101 can receive simultaneously and send signal, and does not interfere with each other each other.
Filtration module 105 is connected between this output 1013 with antenna 104, this filtration module 105 is for the signal of non-first frequency range of filtering and non-second frequency range, like this, make this mobile terminal more smooth in the process of Received signal strength and transmission signal, there will not be the phenomenons such as card pauses.
By above-mentioned technical scheme, make this transceiver can ensure the technique effect simultaneously received and dispatched in multiple frequency range at synchronization.
Although describe the preferred embodiments of the present invention, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the scope of the invention.
