Abstract
The present invention discloses a switch for a radio frequency SoC chip, a SoC chip, and a temperature compensation control method. The switch includes a first series branch and a second series branch respectively connected to a first port. The first series branch and the second series branch both include a quarter-wavelength line arranged in series on the corresponding series branch and a MOS tube connected in parallel to the ground; at least one temperature compensation phase shift unit is connected in parallel on the quarter-wavelength line. The present invention achieves phase adjustment of the entire SoC chip by simple voltage control without occupying more space by combining the temperature compensation phase shift unit with the switch architecture. Without occupying extra layout space, the phase adjustment method of the multifunctional SoC chip is more convenient and quick. After determining the margin required for compensation of high and low temperatures, the switch weight of the temperature compensation phase shift unit can be directly fixed and controlled; moreover, this technology is not limited by the process, can be transplanted in parallel, and can be more widely applied to various frequency bands.
