Abstract

The invention discloses a 5G radio frequency test interface box, which comprises a 5G base station simulator interface group, a tested 5G terminal interface group, an expansion test interface group and a path switching assembly used for connecting the 5G base station simulator interface group and the tested 5G terminal interface group, and is characterized in that the 5G base station simulator interface group comprises a plurality of first interfaces used for being connected with a 5G base station simulator; the tested 5G terminal interface group comprises a plurality of second interfaces used for being connected with a tested terminal; the extended test interface group comprises a CW interference source interface, an AWGN noise source interface and a spectrum analyzer interface; the path switching assembly comprises a switch unit arranged between the plurality of first interfaces and the plurality of second interfaces, and is used for switching channels formed between the plurality of first interfaces and the plurality of second interfaces and expanding different test modes of the test interface group; the 5G radio frequency test interface box further comprises adjustable attenuators arranged on all the channels, and the adjustable attenuators are used for achieving attenuation control over signals in all the channels according to the received control signals.

Description

technical field [0001] This application relates to the technical field of 5G radio frequency terminal testing, in particular to a 5G radio frequency test interface box. Background technique [0002] With the advent of the 5G era, base stations use large-scale antenna arrays, and mobile phones also use multi-antenna designs, which can meet the needs of beamforming; therefore, the requirements for RF testing of mobile phones have changed accordingly. In the era of 4G including the previous era, most mobile phones have a single antenna. Even if there are multiple antennas, it is because of the multiple antennas on the frequency band that different antennas are selected in different frequency bands, different operators and different regions; therefore, 4G RF tests are all It is in the SISO state (that is, single receipt and single delivery). Beamforming from 5G requires multiple antennas to work simultaneously, that is, MIMO state, and the phase of each antenna is different; th...
