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 communication transceiver, solve communication 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 communication transceiver, be applied to mobile terminal, comprise duplexer, regulon, control unit, antenna, regulon comprises adjustable match circuit and tunable band-stop filter, regulon is connection control unit and antenna respectively, duplexer comprises public terminal, transmitting filter, receiving filter, reactance circuit, wherein, at least one in described transmitting filter and receiving filter is connected to described reactance circuit, described transmitting filter and receiving filter are all connected to described public terminal, public flirtatious sub-connection 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, series resonator between described receiving filter and public terminal.
Further, described receiving filter and described transmitting filter are surface wave filter.
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 public terminal, transmitting filter, receiving filter, reactance circuit, wherein, at least one in transmitting filter and receiving filter is connected to reactance circuit, and transmitting filter and receiving filter are all connected to public terminal, and public terminal connects 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 communication transceiver in the embodiment of the present invention.
Embodiment
The present invention is by providing a kind of communication transceiver, solve communication 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 communication 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 communication 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 public terminal 1011, transmitting filter 1012, receiving filter 1013, reactance circuit 1014, wherein, transmitting filter 1012 is connected to reactance circuit 1014 with at least one in receiving filter 1013, transmitting filter 1012 and receiving filter 1013 are all connected to described public terminal 1011, public terminal 1011 connects antenna 104.
In a particular embodiment, the signal exported by duplexer 101 public terminal 1011, 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, series resonator between this receiving filter 1013 and public terminal 1011, this receiving filter 1013 and this transmitting filter 1012 are surface wave filter, can ensure that filtering performance is better, thus make this duplexer 101 to receive simultaneously and to send signal, and do not interfere with each other each other, and 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.
