| Abstract: |
| Gain flatness is a basic performance index of the broadband channel，and with a
number of affecting factors, it is also a different design point. Asso
ciated with formula calculation, circuit simulation and three-dimension electrom
agnetic field simulation, this paper analyzes the influences of various factors
in the microwave circuit design to the gain flatness of the channel，then presen
ts the circuit improvement methods for each affecting factor, and finally review
s the cirtical technology and matters needing attention in the actual circuit de
sign guarantee the broadband gain flatness. |
| Key words: electronic reconnaissance system RF front end microwave circuit design broadband channel gain flatness 3D EM simulation |
