Abstract: An circuit board assembly includes a first circuit board, a second circuit board stacked with the first circuit board, and a connection plate connected between the first circuit board and the second circuit board. The connection plate includes a signal transmission part and at least one ground part at a spacing to the signal transmission part. The ground part can be used as a reference ground for a signal transmitted by the signal transmission part, so that the characteristic impedance of the signal transmission part is controllable, and the signal transmitted by the signal transmission part has strong continuity, thereby maintaining good matching performance and reducing an insertion loss caused by characteristic impedance mismatch.

Abstract: This application discloses a communications chip structure, including: a channel selection module, configured to receive an input signal, where the input signal is a signal of a preset narrow bandwidth span or a signal of a preset wide bandwidth span; and a digital baseband module, configured to control the channel selection module to select a first sampling and quantification channel when the input signal is a signal of the preset narrow bandwidth span, or control the channel selection module to select a second sampling and quantification channel when the input signal is a signal of the preset wide bandwidth span. The channel selection module is further configured to send the input signal to the first sampling and quantification channel or the second sampling and quantification channel for sampling and quantification.
