TECHNICAL FIELD
[0001] The present application relates to the technical field of radio frequency circuit board, and particularly relates to a radio frequency circuit board of terminal equipment and a connecting device compatible with different antenna connection modes. BACKGROUND
[0002] At present, the transmission signal of an antenna is adopted by a coaxial seat or a radio frequency test seat. Since different antenna environments result in inconsistent antenna forms of the coaxial seat or the radio frequency test seat, the antenna connection modes of the coaxial seat and the radio frequency test seat are different. One antenna connection mode is a coaxial seat plus a coaxial line and an antenna, and the other antenna connection mode is a test seat plus a spring and an antenna.
[0003] The circuit board of the existing antenna connection mode cannot be adapted to multiple projects (such as the coaxial seat or the radio frequency test seat), that is, the existing antenna connection mode applicable to the coaxial seat and the radio frequency test seat cannot share one circuit board PCB, which easily causes product inventory stagnation. The circuit board of the existing antenna connection mode applicable to the coaxial seat and the radio frequency test seat is required to be designed with two circuits on the circuit board, which increases the layout area of the circuit board PCB. If a small size antenna product is encountered, since there are limited components, the target cannot be achieved. The existing test needs to purchase two different radio frequency test antennas, which is expensive and the wire precision is high and easy to be damaged. CONTENT OF THE INVENTION

[0011] Preferably, the antenna base is a radio frequency test seat, the corresponding matching element is a second resistor, and a signal output connection end of the radio frequency test seat is connected with an input end of the second resistor.
[0012] Preferably, an output end of the second resistor is connected with an elastic connecting piece.
[0013] Preferably, the elastic connecting piece is a spring piece.
[0014] Preferably, the antenna base is a coaxial seat, the corresponding matching element is a first resistor, and a signal output connection end of the coaxial seat is connected with an input end of the first resistor.
[0015] Preferably, the first resistor serves as a ground end.
[0016] Preferably, the coaxial seat is connected with an antenna through a coaxial line.
