The utility model content
In order to solve the problem that the microstrip line cabling brings inconvenience for circuit-board laying-out and device layout in the prior art, the utility model provides a kind of RF repeating device.
The utility model provides a kind of RF repeating device, comprises the sub-miniature B connector that docks with the interface of wireless transceiver, and is fixedly connected mechanism to what the interface of said sub-miniature B connector and said wireless transceiver was fixed.
As the further improvement of the utility model, said fixed connection mechanism comprises shell, and said shell is installed on the said sub-miniature B connector, and said shell can be sleeved on the interface of said wireless transceiver.
Further improvement as the utility model; Said fixed connection mechanism also comprises the joint fixing pin; Said shell is provided with opening, and said joint fixing pin inserts said enclosure from said opening, and said joint fixing pin links to each other with said sub-miniature B connector.
Further improvement as the utility model; This RF repeating device also comprises radio frequency line, IPEX terminal; Said radio frequency line one end links to each other with said IPEX terminal, and the said radio frequency line other end links to each other with said sub-miniature B connector, and said IPEX terminal is used for linking to each other with radio-frequency module.
As the further improvement of the utility model, the interface of said wireless transceiver is wide rapids connector.
As the further improvement of the utility model, this RF repeating device also comprises protection tube, and said protection tube is set in said radio frequency line outer surface.
As the further improvement of the utility model, said sub-miniature B connector is split type the connection with said radio frequency line.
The beneficial effect of the utility model is: because said radio frequency line one end links to each other with said IPEX terminal, the said radio frequency line other end links to each other with said sub-miniature B connector, so replaced microstrip line through radio frequency line.Because radio frequency line need not to be fixed on the pcb board; So the position of radio frequency line is more flexible, so just can not influence the layout of device, the position of yet can limiting module not placing; More need not to consider the problem of electromagnetic compatibility, brought very big convenience for the device layout and the module placement of side circuit.
