Abstract

The invention provides a time sequence control circuit, a time sequence control method and a terminal, the time sequence control circuit comprises a baseband chip, a signal transmitter, a switch, a power coupler and an antenna, and the signal transmitter, the switch, the power coupler and the antenna are electrically connected in sequence; The baseband chip is electrically connected with the signal transmitter through a first control circuit; The baseband chip is electrically connected with the switch through a second control circuit; The baseband chip is electrically connected with the powercoupler through a third control circuit; The baseband chip adjusts a first time sequence parameter of the switch by detecting a time point at which the power coupler is coupled to forward power; Wherein the forward power is power from the switch to the power coupler. According to the invention, the time sequence control circuit is arranged to realize the purpose of dynamically adjusting the switchtime sequence. Therefore, the time sequence control method provided by the invention has a relatively good time sequence control effect.

Description

Technical field [0001] The invention relates to the technical field of circuit control, in particular to a timing control circuit, a timing control method and a terminal. Background technique [0002] With the increasing requirements for network throughput, the number of antennas in mobile phones, computers and other terminals is increasing, and the number of antenna switches matching the antennas is also increasing, and the timing control requirements for the switches are also increasing. Higher. At present, the control of the switching sequence in the terminal is generally implemented through manual debugging before the terminal leaves the factory, which requires a lot of effort and is inefficient. In addition, as the terminal is used, the device will experience varying degrees of aging, and the consistency of the device will also have a more or less impact, which makes the previously debugged switching sequence unable to meet actual needs. It can be seen that the timing cont...
