Abstract:
    The invention is used for testing, calibrating and debugging the RF performance of mobile terminal. The testing interface is located on a PCB and comprises a first microstrip line interface, a microstrip line, a second microstrip line interface, a center through-hole, a coaxial cable, and one or more grounded through-holes on PCB. Wherein, the first microstrip line interface is connected to the second microstrip line through a second microstrip line; the coaxial cable is connected to the microstrip line through the center through-hole, and passes through the through-hole and is distributed on the area closed to the second coaxial line interface; the first microstrip line interface is connected to the external mobile communication transceiver; the second microstrip line interface is connected to the external antenna; the coaxial cable interface is connected to the external testing apparatus.
