Signal processed, each logic control signal is corresponding with two binding posts in route selection module, here by the two binding posts point
It is also known as the first binding post and the second binding post.
It is not the common terminal period of the day from 11 p.m. to 1 a.m in the first binding post and the second binding post, first logic control signal is used
Disconnected in indicating control switch pipe;It is the common terminal period of the day from 11 p.m. to 1 a.m in the first binding post or the second binding post, the first logic control
Signal processed closes for indicating control switch pipe.
Wherein, the first logic control signal corresponding to frequency range and the second logic control signal are each made by technological development people
Member's setting.Specifically, developer first can set an inductance value for the different operating frequency range of different antennae, so that antenna work
Make in a certain working frequency range, the inductance value of the inductor-adjustable apparatus in impedance matching network can be adjusted to corresponding to the channel
Inductance value, the power of antenna transmitting radiofrequency signal is set to reach highest.Then, technological development personnel are for each work frequency
Section, when determining that the inductance value of inductor-adjustable apparatus becomes inductance value corresponding to the working frequency range, switching tube in inductor-adjustable apparatus
On off operating mode, and, route selection module be inscribed line terminals between mode of communicating.If switching tube turns on, by controlling switch pipe
The first logic control signal, route selection module second logic control signal corresponding under the mode of communicating and the work of conducting
The corresponding storage of frequency range is in the control module.If switching tube disconnects, the first logic control signal that controlling switch pipe is disconnected selects
