Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each execution mode of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each execution mode of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following execution mode and amendment, each claim of the application technical scheme required for protection also can be realized.
First execution mode of the present utility model relates to a kind of compatible pcb board, and this compatible pcb board comprises: at least one sharing position; There are at least two kinds of annexations in described sharing position, described sharing position is for being placed with the described compatible printed circuit pcb board different components and parts corresponding when being applied to different frequency range; The annexation that described different components and parts are corresponding different.
Compatible first frequency range of compatible pcb board and the second frequency range in present embodiment, as shown in Figure 1, sharing position 10 is for being placed with the first resistance R1 of corresponding described first frequency range, or the second resistance R2 of corresponding described second frequency range; And, the first resistance and the second resistance to be placed with direction identical.Furtherly, this sharing position 10 comprises the below pin of shared pad 101, a first resistance R1 and the top pin Connection Sharing pad of the second resistance R2 further.
Compatible pcb board in present embodiment is applied to 4G equipment, its local circuit design as shown in Figure 2, one end of R1 is connected to PAB4 (34) port, the other end is connected to duplexer TX (3) end, one end of R2 is connected to PAB2 (32) port, the other end is connected to duplexer TX (3) end, visible, one end of two resistance is all connected to duplexer TX (3) end, these two pins can reduce the space taken on compatible pcb board while using and sharing pad.In addition, compatible pcb board in present embodiment pastes the second resistance R2 when needs use second frequency range (B2) time, when needs use first frequency range (B4) time, paste the first resistance R1, realize change resistance, i.e. flexibly changing frequency range B2 or B4.
The present inventor finds, because pcb board is when corresponding different frequency range, its circuit differences is less, be generally the annexation changing a certain components and parts, may need to change be communicated with the pin of chip, and the component locations that the method for components and parts sharing position makes different frequency range corresponding is constant, that can reduce branched structure and extraneous clutter disturbs situation mutually.
