| Abstract: |
| A Ka-band up-converter module is introduced.Using twice frequency-conversion technique and single local oscillator(LO),L-band 500MHz bandwidth signal is up-converted to Ka-band.By optimizing and using high-performance filter,very-low spurious response is obtained,good phase-noise property and good amplitude vs frequency response are also achieved.Finally,the module is tested,and the design target is satisfied. |
