| Abstract: |
| For the requirements of satellite communication,a design method of harmonic mixing combined with broadband matched filter circuit is presented.By using miniaturized parallel coupled microstrip filter and HFSS and ADS,a miniaturized extremely high frequency(EHF) up-converter is designed,thus realizing the integrated design of frequency conversion,filtering and driving amplifications.The module is featured by high integration,simple structure and small size.Test results show that its technical indexes meet the design requirements. |
