In the value of target power.
Specifically, if control module is also used to the first power being reduced to target power when control module is limiter
Later, the signal that power is reduced to target power is exported to diversity module.
It is appreciated that the maximum power by the limiter can be limited by limiter.
In general, signal can be with the power of very little when the amplitude of signal power is less than the threshold power amplitude of limiter
Decaying is by limiter, and when the power of signal is more than the threshold power of limiter, limiter makes the power of signal that can decay
For threshold power, even if input power increases, it is threshold power that the power of the output signal of limiter is also permanent.
Specifically, limiter can be microwave limiter.

Whether the power of the signal of main collection module output is greater than first threshold (it should be noted that main collection module exported in reason device
The power of signal is identical with the power for the signal that main collection module is crosstalked into diversity module).If processor determines main collection module output
The power of signal be greater than first threshold, then processor control second switch closure (the i.e. first end and the of control second switch
The second end connection of two switches)；If processor determines that the power of the signal of main collection module output is less than or equal to first threshold,
Processor control second switch disconnects (i.e. the first end of control second switch and the second end of second switch disconnects).
In general, the performance number for being leaked to the signal of diversity module is typically much deeper than the function of the received normal signal of diversity module
Rate value.In the embodiment of the present invention, it can determine that the signal for being leaked to diversity module is big by the power of main collection module output signal
Power.
