Abstract

In the fifth-generation (5G) new radio specifications, large signal bandwidth e.g. 400 MHz for frequency range 2 (FR2), is expected to be utilized. Therefore, there is a need to develop channel emulators that can support such large bandwidth. In this paper, we revisit the band-stitching scheme, i.e. combining multiple logic channels of small bandwidth to form a larger total bandwidth.We put a focus on the calibration stage of this scheme, and the effect of the phase jump at the junctions of adjacent subbands on the stitching performance is investigated through simulation.
