Abstract:

Mathematical models are established according to the basic theory of lowpass filter prototype,and the microstrip hairpin bandpass filter of seventh order in the X-band is designed using the serenade software,with a central frequency of 11 GHz and bandwidth of 800 MHz.The got-up microstrip circuit is tested,and the testing results show that the filter meets the demand of design.

Key words: X-band;hairpin;bandpass filter;coupling coefficient
