It is as follows.
Fig. 2 a are refer to, is the reality for being arranged at a kind of RF receiving/transmission device on double-sided PCB that the utility model is provided
Apply the schematic diagram of mode.As illustrated, RF receiving/transmission device 110 includes some elements 10, element 10 is arranged at double-sided PCB
On 120.
3 are please see Figure, are a kind of circuit connection diagram of the implementation method of RF receiving/transmission device that the utility model is provided,
As illustrated, the element 10 of RF receiving/transmission device 110 includes amplifier 2, the first wave filter that transceiver 1 and transceiver 1 are connected
3rd, the second wave filter 4 and the emitting mould train 5 being connected with the first wave filter 3 and the second wave filter 4 respectively, the first wave filter 3 is also
It is connected with transceiver 1, the second wave filter 4 is also connected with amplifier 2.Fig. 2 b are refer to, is that the first of the utility model offer is real
Apply the schematic diagram that a kind of RF receiving/transmission device in example is arranged on double-sided PCB.Transceiver 1 and amplifier 2 are respectively arranged at double
One of which sets with emitting mould train 5 in the two sides of face circuit board 120 such as A faces and B faces, the first wave filter 3 and the second wave filter 4
The one side and the wave filter 3 of transceiver 1 and first for being placed in double-sided PCB 120 are arranged at the same face of double-sided PCB 120, set
In the element 10 and the element 10 being arranged on the another side of double-sided PCB 120 in the one side of double-sided PCB 120 be wired connection,
Preferably the wired connection of via, i.e. connecting line are by the perforate 8 on double-sided PCB 120；In other feasible embodiments,
Can not be via connection.Also, it should be noted that in other feasible embodiments, transceiver 1 and amplifier 2 are respectively provided with
In the two sides of double-sided PCB 120 such as A faces and B faces, the first wave filter 3, the second wave filter 4 are arranged at double with emitting mould train 5
The same face of face circuit board 120, will hereafter be specifically described.
Wherein, emitting mould train 5 is used to launch and receive signal, the integrated some switches of emitting mould train 5, each switch correspondence one
Emitting mould train 5 is switched to the passage of matching when individual frequency range, transmitting and reception signal, realizes the transmitting and reception of radiofrequency signal.The
One wave filter 3 is filtered for receiving radiofrequency signal by antenna to emitting mould train 5, by radio frequency after interference signal is filtered
