With reference to the accompanying drawings, the HF link of preferred embodiment of the present utility model and the one-piece type daughter board of common line are described.
As shown in Figures 2 and 4, the utility model comprises: antenna interconnecting piece 100; Substrate connecting portion 300, it is connected to mainboard; And transmission lines portion 200, it connects between antenna interconnecting piece 100 and substrate connecting portion 300, and is printed with HF link and common line, thus can transmit high-frequency signal and normal signal.
In the past, connector is separately installed with the connecting portion of HF link 220 in the connecting portion of antenna interconnecting piece 100 and common line 210, antenna interconnecting piece 100, but the utility model is installed on a transmission lines portion 200 common line 210 and HF link 220, circuit number itself is reduced, thus the interference of connector generation and the loss of signal can be reduced.
Preferred transmission lines portion 200 is formed by flexible material.
Difference in height can be there is between the antenna interconnecting piece 100 and mainboard of daughter board.Therefore, the transmission lines portion 200 connected between antenna interconnecting piece 100 and mainboard should have soft material.For this reason, transmission lines portion 200 is made by flexible printed circuit board.
As shown in Figures 2 and 4, preferably in the splicing ear 310 being formed at substrate connecting portion 300, the terminal adjacent with the terminal being connected to HF link 220 is earth terminal.
During in order to transmit high-frequency signal, can prevent high frequency radiation signal from flowing out to outside or disturbing and flowing into from outside, need the terminal adjacent with the terminal being connected to HF link 220 make earth terminal and make it ground connection.In the terminal being connected to HF link 220, one or two terminal that left and right adjoins is formed as earth terminal, could obtain this effect.
The effect of each terminal of the substrate connecting portion 300 shown in Fig. 4 is as follows.
NC (NoConnection): the pin do not connected
VCC: amplifier (LNA) power supply
PON (Poweroncontrol): amplifier (LNA) operates controller
EN (Enable): RF switch activator
CT1, CT2 (Control): RF switch operation controller
VDD:RF Switching Power Supply
G (Ground): ground connection
RF (RadioFrequency): HF link
Preferred antenna connecting portion 100 and substrate connecting portion 300 and transmission lines portion 200 form as one type, and share can transmit the signal transport layer 410 of the signal of telecommunication, the top being laminated in signal transport layer 410 and bottom dielectric layer 420 and be laminated in the top of dielectric layer 420 and the ground plane 430 of bottom in the mode of the outside that can surround dielectric layer 420.
So antenna interconnecting piece 100 and substrate connecting portion 300 and transmission lines portion 200 are made into one-piece type, thus the interference that connector can be made to occur and the loss of signal minimize.In the past, antenna interconnecting piece 100 is also attached with connector, is connected with transmission lines portion 200, thus interference and the loss of signal many, but the utility model is connected to transmission lines portion 200 incessantly due to the circuit being printed in antenna interconnecting piece 100, thus can address this is that.Be printed with substantive circuit at signal transport layer 410, dielectric layer 420 prevents the short circuit of circuit, and ground plane 430 can make circuit ground, and this is common known technology, thus omits and is described in more detail.
Preferred antenna connecting portion 100 comprises the C clamp 110 that is connected with antenna 500 and the passive component 120 with C clamp 110 transceive electrical signals, also comprise more than at least one in RF switch 130, amplifier 140, filter 150, thus can between connected with passive element 120 and transmission lines portion 200.C clamp 110 is directly connected with antenna 500, transmit wireless signal to antenna or accept to transmit wireless signal from antenna, passive component 120 is in order to improve antenna performance, be configured more than to comprise in resistance (Resistor), inductor (Inductor), capacitor (Capacitor) a certain, thus the signal of telecommunication can be mated by accurate impedance adjustment.
RF switch 130 only carries out opening and closing to the signal needed in multiple high-frequency signal, amplifier 140 (LowNoiseAmplifier) suppresses unwanted interference, signal needed for only amplifying, passes through and installing filter 150 (SurfaceAcousticWaveFilter to only make the frequency of set frequency band; Surface Acoustic Wave Filter).In the examples in the drawings, form although all installed these, as required, the part also can omitted in RF switch 130, amplifier 140, filter 150 is formed.
Another feature of the present utility model is, at antenna interconnecting piece 100 and substrate connecting portion 300, is formed and is laminated in the top of ground plane 430 and the reinforced layer 440 of bottom in the mode can surrounding ground plane 430.
Transmission lines portion 200 needs flexibility to a certain degree, can be connected to mainboard, but adheres to reinforced layer 440 in antenna interconnecting piece 100 with substrate connecting portion 300, prevents distortion, thus can keep form.If do not have this reinforced layer 440, then the durability of antenna interconnecting piece 100 and substrate connecting portion 300 can be too low.
Above with reference to accompanying drawing, describe embodiment of the present utility model, but the utility model person of ordinary skill in the field is appreciated that the utility model does not change its technological thought or necessary feature, can implement with other concrete form.
Therefore, the embodiment of above description is interpreted as in all respects just example and non-limiting.Compared with described detailed description, scope of the present utility model is represented by following claims book, and the form of all changes that the meaning of accessory rights claim and scope and its impartial concept derive or distortion should be interpreted as being contained in scope of the present utility model.
