Block further includes 1.2GHz filter, 2.4GHz filter, the first power amplifier and the second power amplifier；
After the 1.2GHz filter is used to be filtered the baseband signal that the frequency point is 1.2GHz, then input described first
Power amplifier；
First power amplifier is used to carry out power amplification to by the baseband signal of filtered 1.2GHz, and by power
The baseband signal of amplified 1.2GHz is as output；
After the 2.4GHz filter is used to be filtered the baseband signal that the frequency point is 2.4GHz, then input described second
Power amplifier；
Second power amplifier is used to carry out power amplification to by the baseband signal of filtered 2.4GHz, and by power
The baseband signal of amplified 1.2GHz is as output.
9. a kind of more radar jamming performance detection systems as claimed in claim 7, which is characterized in that the down coversion mould
Block further includes power amplifier, when the frequency point of the interference signal is within the scope of 2GHz~12GHz, judges the interference signal
High frequency section whether be less than preset value, if being less than, by the interference signal pass through the power amplifier carry out power amplification
Afterwards, then with the local oscillation signal it is mixed.
