Power detection can be carried out by coupling device below, if coupling device can't detect output signal, illustrate that WTR outputs are problematic,
Conversely, then illustrating that WTR outputs have no problem；
Step 3, in the case where WTR outputs have no problem, radiofrequency signal can amplify through PA, and the signal that will amplify
Output, due to PA power dissipation ratios itself it is larger, so be known that whether PA works by temperature detector, as whether just working
Often, need to carry out temperature test to different PA gains in advance, draw the temperature curve under different gains, then the temperature with this
Contrasted, can be learnt whether PA work is normal；
Step 4, in the case of PA outputs are normal, the signal amplified through PA can flow RF switch, if radio frequency is opened
Close normal work, then the coupling device behind RF switch will detect that power output, if RF switch does not have normal work
Make, then coupling device will not detect power output；
