Contact connection.In the case where the mobile terminal is in transverse screen state, the first contact and third contact of single-pole double-throw switch (SPDT) 3
Connection.
In specific implementation, the signal transmitting and receiving end can also be referred to as " integrated receive and transmitting terminal ", () for example: it is integrated
There are radio-frequency transmissions (Transmit, TX) and main collection to receive integrated reception and the transmitting terminal of (Primary Receive, PRX)
It (TRX), can be simultaneously for realizing the signal reception of mobile terminal and signal transmission function；The signal receiving end can also be with
Referred to as " end RX ", it can be used to realize the signal receiving function of mobile terminal；The single-pole double-throw switch (SPDT), which is opened, to be referred to as
For " SP2T (Single Pole 2Throw, single-pole double throw) "；The N knife N throw switch can be referred to as " NPNT (N Pole N
Throw, N knife N are thrown) ".
In addition, at least partly antenna adjacent first side and second that is distributed in the mobile terminal in N+1 antenna 1
Side, such as: it may include the top and side that some antennas is distributed in mobile terminal in the N+1 antenna 1；Alternatively, institute
State may include bottom end and side that some antennas is distributed in mobile terminal in N+1 antenna 1.It should be noted that the N+1
There can also be some antennas to be distributed in third side or the four side of mobile terminal in a antenna 1, such as: 3 antennas point
Not Wei Yu mobile terminal top, bottom end and a side etc., be not specifically limited herein.
It should be noted that the N+1 antenna 1 includes first antenna 11 and N number of antenna other than first antenna 11
N number of antenna 12 is only illustrated with an antenna in 12, Fig. 1, in practical applications, N number of antenna 12 may include 2 antennas, 3 days
Line etc. is arbitrarily more than or equal to the antenna of 2 quantity.
In practical applications, since the first side is top or bottom of the mobile terminal under vertical screen state
End, then the second side adjacent with the first side is necessarily located at side frame of the mobile terminal under vertical screen state.Separately
Outside, under vertical screen state, user often holds the side frame of mobile terminal with one hand, to make the day being located on first side
The signal quality of antenna of the signal quality of line than being located on the second side is good.Under transverse screen state (such as: user is to shifting
Dynamic terminal carries out during mobile phone games etc.), user often with the hands holds the both ends of mobile terminal, to make to be located at first
The signal quality of antenna on side is than the poor signal quality for the antenna being located on the second side.
It should be noted that insertion loss of the insertion loss of the single-pole double-throw switch (SPDT) 3 than the N knife N throw switch 4
It is small.Such as: the structure of single-pole double-throw switch (SPDT) is simpler than the structure of three knives, three throw switch.It is obtained through experiment, single-pole double-throw switch (SPDT)
Insertion loss is less than or equal to 0.3dB (decibel), specifically: 0.2~0.3dB, and the insertion loss of three knives, three throw switch is big
In or be equal to 1dB, specifically: 1~1.2dB.It follows that being penetrated in compared to the prior art using the control of N knife N throw switch 4
Connected state between the signal transmission port of frequency front-end module 2 and each antenna in present embodiment, is opened using single-pole double throw
The connected state between the signal transmission port and each antenna of 3 control RF front-end modules 2 is closed, radio frequency path can be reduced
Insertion loss is able to ascend the signal quality of mobile terminal using signal processing circuit provided in an embodiment of the present invention.
In present embodiment, in the case where the mobile terminal is in vertical screen state, the of control single-pole double-throw switch (SPDT) 3
One contact is connected to the second contact, so as to keep away so that signal transmitting and receiving end is connect by single-pole double-throw switch (SPDT) 3 with first antenna 11
Exempt from signal transmitting and receiving end to connect by the biggish N knife N throw switch 4 of insertion loss with first antenna 11, to reduce first antenna
The insertion loss of 11 radio frequency path reaches signal quality of the radio frequency path for improving signal transmitting and receiving end under vertical screen state
Effect.
In addition, in the case where the mobile terminal is in transverse screen state, control the first contact of single-pole double-throw switch (SPDT) 3 with
Third contact connection, to enable signal transmitting and receiving end to connect with any antenna in N number of antenna 12, so that it is guaranteed that signal transmitting and receiving
The radio frequency path at end carries out radio signal transmission by a good antenna of signal quality in N number of antenna 12 under transverse screen state,
Achieve the effect that promote signal quality of the mobile terminal under transverse screen state.
It should be noted that the N knife N throw switch 4 is also used to divide the N-1 signal receiving end and N number of antenna 12
It does not connect.And the signal quality parameter by detecting each antenna, best one antenna of signal quality is selected for holding
The rf signal reception and/or emission of radio frequency signals function of row mobile terminal.
In addition, the first contact and the second contact of single-pole double-throw switch (SPDT) 3 connect in signal processing circuit as shown in Figure 1
It is logical, herein only as an example, in specific implementation, single-pole double-throw switch (SPDT) 3 can also be controlled and be connected to the first contact and third contact.
In specific implementation, in the case where the first contact of single-pole double-throw switch (SPDT) 3 is connected to the second contact, single-pole double-throw switch (SPDT) 3
First contact is not connected to third contact；In the case where the first contact of single-pole double-throw switch (SPDT) 3 is connected to third contact, hilted broadsword
First contact of commutator 3 is not connected to the second contact.
In embodiments of the present invention, under vertical screen state, by signal transmitting and receiving end and it is located at described by single-pole double-throw switch (SPDT)
The first antenna connection on the top or bottom end of mobile terminal, avoids the radio frequency path at signal transmitting and receiving end by N knife N throw switch
And biggish insertion loss is caused, achieve the effect that the communication quality for promoting the mobile terminal；Under transverse screen state, pass through N
Signal transmitting and receiving end is connect by knife N throw switch with other antennas, is avoided in transverse screen operating process, and antenna is by the holding of user
Firmly, achieve the effect that the communication quality for promoting the mobile terminal.
Referring to Fig. 2, be the two of the structure chart of signal processing circuit provided in an embodiment of the present invention, the signal processing circuit
Applied to mobile terminal, as shown in Fig. 2, signal processing circuit provided in an embodiment of the present invention and signal processing as shown in Figure 1 electricity
The difference on road is: signal processing circuit as shown in Figure 2 further include: double-point double-throw switch 5 and the second antenna ANT1, and radio frequency
